Sure! More than 400mg is not recommended and may lead to overdose symptoms. (Less for teenagers and pregnant women.) With strong coffee, 8 cups can easily total more than 1000mg of caffeine. Mild over consumption of caffeine causes known problems like dizziness, anxiety, and headaches. More severe overdose is things like irregular heartbeat and vomiting. https://www.healthline.com/health/caffeine-overdose https://www.healthline.com/health/caffeine-overdose The other problem with large coffee intake is that the acidity of coffee long term can be bad for your stomach and lead to or contribute to heartburn and ulcers. https://www.manhattangastroenterology.com/coffee-digestion/ https://www.manhattangastroenterology.com/coffee-digestion/ Those two links are just from super quick first Google result searches, but these downsides of caffeine & coffee are pretty well known. Possibly unrelated tangent, but I read once that 70 cups of coffee is expected to be in the vicinity of a fatal overdose. First Google result, this article even suggests maybe ~25 cups: https://www.vice.com/en_us/article/exmwka/how-much-caffeine-will-kill-you-127 https://www.vice.com/en_us/article/exmwka/how-much-caffeine-...

  I have first hand experience with near overdose. It was after a late shift. I was at Denny's with a friend for a couple hours. The waitress would bring a cup, I'd drink it, then she'd refill it. I got home. Feeling ... not very good at all. My friend was worried. Maybe you had too much coffee? Call poison control. That's crazy! ... Okay, I will. "I think I might have OD'ed on coffee, is that possible?" Agent: How much did you drink? Me: I don't know was at Denny's for a couple hours or so, constantly drinking refills, maybe 14 or 15 cups? Agent: That'd do it. I waited out the night. Body felt incredibly tired after a full day of work, but my brain absolutely would not fall asleep. It was a horrible experience. You definitely can OD on coffee.
