Do you mean 2-3 liters?

As a mentally ill vampire, I try to only feed on coffee drinkers.

I've been self-medicating ADHD with multiple cups of coffee a day since I was 17. I'm in my early 30s now, and after getting on Vyvanse, have reduced then given up coffee. I realised that coffee was the reason for my anxiety which builds up towards the end of the day.

I reduced my coffee down to 1 espresso per day two months ago, and quit entirely two weeks ago. I'm still on stimulants, but Vyvanse treats ADHD much better and has fewer side-effects.

Yesterday I drank a whole pot myself then had another cup or two. Keeps me in the game.

Where does that put me? Caffeine poisoning or immortality with no in between?
