i have about 3 tough work days a week. so can get pretty tired and just want to sleep on off days but that is obv not good use of time.
so I take about 3 doses of 300 mg of caffeine every other day. Not everyday.
What do you think? Some say not to go over 400 mg, some 600, some say 1000. For me i take it every other day 900 mgs.
