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.
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.

He starts out as a Functional Addict, since he's quite clever and even exploits his reputation to Play Drunk.

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.

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.

She normally cuts her alcohol with hydra venom.
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, is heavy on the drink. Yet they don't seem to be intoxicated very often, or at least not debilitated by it.

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.

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. Usually Klingon physiology fights off the negative effects of alcohol, but she'd consumed so much that even Klingon biology couldn't cope.

In Treasure Island, almost all of the pirates and Mr. Arrow. Billy Bones's stroke at the beginning is attributed to drinking little but rum at the Benbow Inn, and Captain Flint was allegedly killed by rum as well.
