In 365 Days, Laura drinks a lot of alcohol and gets drunk and/or hungover several times per book. When things start going wrong with her life, she tends to reach for the booze. She even drinks while pregnant and mixes alcohol with painkillers. Notably, this was heavily toned down for the films.

The Andromeda Strain: One of the two survivors of the town of Piedmont being slain by the titular biological threat is Peter Jackson, the town drunk. It's noted that all of the drinking has given him a bleeding ulcer, which drives him to drink to deal with the pain, and he is so poor from all the drinking he has taken to drink stove alcohol because that's all he can afford. Ironically, this is what saves him from being killed by Andromeda - his blood chemistry is so shot from all the drinking (very high blood acid levels) that the alien virus (which can only survive within a very narrow PH level in the human body) was destroyed.
In Apathy and Other Small Victories, Shane is almost completely unable to deal with the rest of the world without getting blitzed out of his mind.

This is perhaps the natural state of the Ramkin patriarchs, as described in Snuff. Antics like drunkenly handing out lavish (if occasionally red-hot) tips and swilling a cask of sherry in public after winning a bet earned them an odd sort of respect from their servants, of the "our drunk old lord can beat your drunk old lord in a drinking contest" variety.
Eileen's father has such a drinking problem that he is confined to the house due to being too belligerent and delusional to work as a police officer, drive a car, or even walk around the neighborhood. He drinks at least a bottle of gin a day and spends all his time hallucinating about mobsters and verbally abusing Eileen.

The Family Tree Series has Zander, Abby's husband. He drinks heavily and Abby is clearly upset with it and tells him not to do so in front of the children—which he does anyways, and often where Dana notices (though as a Daddy's Girl she takes his side over her mother's, even if she never says so). It ends up resulting in his death when Dana is ten when after a dinner party he drank heavily at, he drunkenly chases his flyaway hat over the railing of a moving ferry and falls into the water, drowning in the process and widowing Abby. Dana blames not only herself, but her mother Abby, saying she could have been there to help but was off being sick in the bathroom. A few months later she learns this is because Abby was pregnant and struggling with severe Morning Sickness; she later has their last child, Nell.

GONE: Orc becomes an alcoholic after the events of the first book.
In Guns of the Dawn, Father Burnloft, the priest attached to the army in which Emily is sent to serve, is habitually drunk. It may simply be a consequence of all the death he's seen, but soldiers who've seen just as much and now have to listen to him stagger through the funeral service for their dead comrades don't necessarily have much sympathy.
Harry Hole, the protagonist in a series of crime thrillers by Norwegian Jo Nesbø. A detective in the Oslo Police Department, Harry is usually tolerated by his superiors and colleagues despite his habitual alcoholism and unorthodox methods because he is a brilliant detective.
Winky the house elf, who, being an elf, gets drunk on butterbeer.
And Professor Trelawney with her cooking sherry. Though it only started because Umbridge put her on probation.
Hagrid is heavily implied to be one. He swears at least once that he'll never drink again (it doesn't take), and the trio end up taking care of him more than vice versa.

Amelia the Planeswalker, eldest surviving daughter of Bethesda the Heartstriker, one of the two greatest dragon mages in the world, and unarguably one of the most powerful entities to walk this or any other plane, is mostly known for being an unreliable drunk. Considering her own mother has been trying to murder her for centuries for stupid reasons, this is understandable. Of course, as a dragon, it takes a lot to get her drunk. She normally cuts her alcohol with hydra venom.
In the sequel series DFZ, Amelia is the Spirit of Dragons, the immortal god of all dragonkind. She's still a drunk. Opal is instructed on how to get her attention using cheap alcohol. Opal is worried, because even she would be insulted if someone tried to summon her with such cheap offerings, but she's barely finished when Amelia has already appeared and is drinking the offerings.
The Hunger Games gives us Haymitch, who is perpetually shown drunk or at least mildly intoxicated, largely an effect of the horrors the Hunger Games he competed in. He is an alcoholic to the point where the main characters worry about him after police shut down the local liquor brewers.
A relatable example with Kyle Griffin, the protagonist of The Impairment where he turns to booze to help lower the stress he feels after being framed for the murder of his roommate by an extra-terrestrial. Needless to say, it's not much of a comfort as that's where all the trouble always starts.
Jakub Wędrowycz stories: Jakub, as well as most of his home village, this being set in Poland and with a full-on My Country Tis of Thee That I Sting, is drinking a lot. Yet they don't seem to be intoxicated very often, or at least not to a debilitating degree. And even if he is, Jakub's horse can act as a Designated Driver and get him home.
James Bond tends to drink a lot, though more so in the novels than in the movies. He's constantly guzzling down on booze, and sometimes likes to mix it with coffee or water.

Hunn Raal, from the Kharkanas Trilogy, who is one of the commanders in Urusander's Legion. Nobody likes him and his constant drinking makes everyone think he's a useless fool. Evidence shows it's Obfuscating Stupidity.
Several Stephen King protagonists (especially the writers), have this particular affliction, most notably Jack Torrance from The Shining (also Danny Torrance in Doctor Sleep) and Jim Gardener from The Tommyknockers. King himself went through alcoholism and recovery during the course of his career, so that's not too surprising. Ironically, many people think he wrote better books before he stopped drinking. In his memoirs, King himself denies that there's any relationship between being a good writer and being an alcoholic. He mentions in his memoirs that he has no recollection of writing Cujo — that was one pretty impressive bender there.
The Last Full Measure references Ulysses S. Grant's previous alcoholism and explains its origins. He's shown almost going Off the Wagon after the disastrous assault on Cold Harbor, but one of his aides intervenes. General Ledlie also appears and gets no sympathy, since his inebriation in two battles resulted in disaster for his men.

Several characters from A Song of Ice and Fire. King Robert Baratheon spends as much time as he can with a comfortable buzz... mainly because he's depressed as hell, and it's his way of coping. It bites him in a number of ways. Cersei becomes one over the course of the series, which is part of the reason Jaime finds her increasingly repulsive. Sandor Clegane has long been one, and even in the second book is rarely seen sober; in the third book, he basically wanders around getting drunk when and wherever possible (with a 10-year-old in tow, no less). It's his downfall. Turns out it's kind of hard to fight when you're that drunk. There's Tyrion Lannister, who is a high-functioning version of this, and is always looking for more wine. But, as the series illustrates, the more drunk you are, the better your chances of catching the Idiot Ball, even if you don't go full-on Alcohol-Induced Idiocy. Even you, Tyrion.
Stag Preston in Spider Kiss, and it just makes his other negative traits that much worse.
The ditzy popstar Cherry Pye in Carl Hiaasen's book Star Island drinks constantly and to excess, often resulting in a disastrous aftermath, like Axl Rose headed zebra tattoos, which must be cleaned up by her handlers.
Kurak in the Star Trek: Klingon Empire novels. At one point, she refuses to believe that she has alcohol poisoning, because as far as she's concerned alcohol is only a poison to "weak" races such as humans.

Arthur Huntingdon in The Tenant of Wildfell Hall, to the point that it ends up killing him before he's forty.
Arthur's mother in Theatricawho falls of a roof, piss drunk, and dies.

She even had some liqueur lying around for a young Amory to take a sip of and get drunk when he was left alone in a hotel room (which secretly amused her). Shortly after Amory's surgery to get his appendix removed, Beatrice had another nervous breakdown with the symptoms being similar to that of alcohol withdrawal delirium, implying she was trying to stop drinking at one point.
Renzo Leoni in A Thread of Grace occasionally gets so drunk that he'll pass out in the bed of a strange woman and has to check the fabric of his clothes and the class of woman to remind himself which fake identity he had adopted the night before.

Up Schitt Creek: Glen Doyle drinks heavily as a coping mechanism to get over the death of his sons in the Civil War. He eventually sobers up in order to find his kidnapped wife and daughter, and after he nearly choked Jessie to death during what he thought was a dream sequence.
Adrian Ivashkov from Vampire Academy, is addicted to alcohol, played with in that it's more to block out spirit.
Eren dom Hastrell of The Witchlands is drunk most of the time, having descended into alcoholism after he was dishonorably discharged from the Elite Army he used to be a part of. Or so he wants everyone to think.
◊, including martinis, beer, whisky, bourbon, cocktails, gin and champagne. A tragic example comes in You Only Live Twice, where he goes completely off the rails after Tracy's death in On Her Majesty's Secret Service, drunkenly wandering about London, thinking irrationally and getting multiple hangovers on a daily basis.
