"One of these drinks would have had my eyeballs vibrating out of my skull. He's had three and he's still fallen asleep."Someone Must Have Caffeine (or some other stimulant)—but is so exhausted, even that won't ward off sleep. This is Truth in Television for two reasons: First, if a person is sufficiently exhausted, no amount of caffeine or stimulant will keep them awake. Second, people develop a tolerance for caffeine leading to diminishing returns on each subsequent dose. On people who are naturally "wired" to a certain degree, like those with ADHD, especially those who have been on medication for a long time (since ADHD medications are typically powerful stimulants that make caffeine look weak by comparison), caffeine may have drastically limited effects, so a dose that would make most people into jittery insomniacs may just cause them to yawn less for an hour. If it's because someone switches to decaf, it's not this trope. Contrast Caffeine Bullet Time.
— Maxwell Post, discovering why Bill Raibert won't answer his phone, Freefall
- A Nightmare on Elm Street 3: Dream Warriors had a character actually eating coffee grinds in an attempt to stay awake and avoid Freddy from trying to kill her in her dreams. It did not work, at all.
- In Before I Wake, young Cody's dreams manifest in real life. He is so terrified of his night terrors of a being he calls the "Canker Man" that he frequently drinks soda and pops caffeine pills at night to stay awake.

- Peripheral plot line in House, M.D. episode "Help Me"—the medical mystery of the week—stems from the crane operator apparently having fallen asleep while working, despite being literally overloaded with caffeine (due to ingestion of lots of coffee and caffeine pills).

- The "Engaged Part 1" episode of NCIS has the team having to work overtime on the Mystery of the Week, and Gibbs at one point walks in on Abby's lab to see a huge pile of empty Caf-POW! cups on her desk. She says she's written an algorithm to determine how long she can go on like that and that she's got about five minutes before she becomes "Zabby or zombie Abby".
- The children of the two rival houses of Step by Step have a bet to see who can stay up for the longest period of time. At one point, Karen is about to crack, and Dana pushes her to keep going and drink more and more coffee ('Coffee is our friend!'), even as its effectiveness is diminishing.

- Whateley Universe: An effect of the Regenerator power, as said in Round and Round (Part 2):
I stared into my half-empty cup of coffee, letting out a faint sigh. Mom had never liked to let me drink coffee, saying that it made me too hyper. Jackie and Emily didnít care and let me drink as much as I wanted. This was actually my third cup today, but I still didnít feel it. My go juice no longer provided any go.ďStupid regeneration,Ē I muttered in annoyance. Iíd already built up an immunity to caffeine, and even if I hadnít, my power would have wiped it out of my system too fast to get much effect.
