To keep things short. I just recently quit. Been a whole week without caffeine. I did get headaches. I took ibuprofen and that relieved the headaches. You are drinking 2 to 3x as much as I did btw. Yours looks more expensive than mine too. You could save a few bucks if ya quit. I believe in you. Don't give up. Treat it loke alcohol. Don't drink no matter what! (COFFEE)
