I used to drink yerba mate almost daily (higher caffeine content than average coffee) because I thought it kept me in the game. At one point I had to go on very strict diet due to health issue so took one week break. I never felt urge to drink it again, my avg energy levels are higher, and anxiety levels lower since stopping (2 months so far)
I drink roughly a pot of coffee a day. Keeps me in the game.
Just one more at dinner is not going to keep me awake at night. Maybe another pot, but that's still a maybe.
