good lord man... That's allot of coffee. Hmm. good question. I'd say it depends on your dose. I go up to 50mg then back down. 20, 20, 30, 30, 40, 40, 50, 50 and back down. then two weeks off. I do NOT recommend going higher than 50mg. and definitely do the 2wks on 2wks off. keeps you from building a tolerance to it.
