* A girl in ''MandatoryRollerCoaster'' asks "Have you ever drank so much coffee that your pee smells like coffee?"
* Subverted in ''{{PVP}}'', where Brent Sienna is initially [[http://www.pvponline.com/comic/2005/02/18/feb-18-2005/ addicted to coffee]] but has to give it up for health reasons. Then when PVP magazine is in crisis, and Brent insists on coffee to "give him his edge", it turns out [[http://www.pvponline.com/comic/2005/03/19/sat-mar-19/ it was decaf]] in a classic example of "[[MagicFeather the magic was in you all along]]."
* ''AntiheroForHire'' normally has the action taking place at night. When the hero has to get up during the day, [[http://www.antiheroforhire.com/d/20050715.html he needs his coffee]]. He ends up spending most of the arc looking for some.

* Vanamonde von Mekkhan from ''Webcomic/GirlGenius'' spends all his time in a coffee shop in Mechanicsburg, and certainly does enjoy his coffee.

---> The second (Heterodyne girl) is making coffee... [[MadScientist there have been two explosions already]].
* [[http://www.questionablecontent.net/view.php?comic=800 This]] ''QuestionableContent'' shows a [[JustifiedTrope justified]] example. Really surprising the trope doesn't crop up more often since QC centers around a ''[[LocalHangout coffee shop]]''.
** In another strip, someone offers Faye coffee first thing in the morning, and she drinks it straight from the carafe.
* From ''Webcomic/TheOrderOfTheStick'', the prequel book ''StartOfDarkness'' reveals that before he became a lich, Xykon loved coffee (he even refused to let Redcloak and Right-eye tell them about their plan until he had some), and extolled the virtues of bad coffee (as he puts it, when you drink truly horrible coffee, you force yourself to re-experience every good cup you've ever had to block out the slop you're currently pouring down your throat). When he tries to drink his first cup of coffee after becoming a lich and discovers he can no longer taste coffee, he reacts... poorly.

* ''Webcomic/TheWhiteboard'' is a great example. The main character "Doc" brews his own Mt Dew because the normal stuff is too weak.
** One arc involves Doc drinking energy shots by the quart after he runs out of Dew and coffee, resulting in one of the more "realistic" portrayals of CaffeineBulletTime.
* An early ''Webcomic/OzyAndMillie'' strip, from when the writer admits she was going for the newspaper comic audience.
-->'''Millie:''' I don't care if it does stunt my growth. [[PunctuatedForEmphasis I. Need. COFFEE.]]
* Lynette from ''Sharing a Universe'' quickly got hooked on the stuff and turned herself into [[http://sharingauniverse.comicgenesis.com/d/20031020.html "The Coffee Hunter"]] stalking the city after those precious beans when Alison decided to intervene and stop supplying her addiction.
* ''Webcomic/{{Freefall}}'':
** Florence Ambrose tends to take exception to having her coffee taken away, [[http://freefall.purrsia.com/ff500/fv00421.htm as only a carnivore can]]. She also explicitly cited the availability of coffee as a benefit of restoring power to Sam's ship.

* Monica of ''WapsiSquare'' gets like this [[http://wapsisquare.com/comic/charades/ sometimes.]]
* In ''GeneralProtectionFault'', part of the test to see if a geek is '[[ChosenOne The One]]' is a test of caffeine addiction. Fooker passed it by enjoying coffee that has congealed to the consistency of tar. Sharon passed it by chewing coffee beans and washing them down with more coffee.
* In ''Webcomic/SluggyFreelance'' when Torg and Riff briefly got regular 9-to-5 jobs they became coffee zombies in the morning.
** Later, making everyone addicted to high-octane "coffee" (that is explosive in its undiluted state) is just one form of GovernmentDrugEnforcement in 4U City. And cutting off the coffee pipeline sets off a massive revolution.
* In one contemporary arc strip of ''ArthurKingOfTimeAndSpace'', Arthur, who is decidedly NotAMorningPerson, is shown pouring coffee on his cereal. It's left ambiguous how intentional this is.
