I can manage to drink 64 oz but when I do i find myself having to go to the potty like every 5 minutes which doesn't really work out when youre in school or at work... lol... but yeah i'm in...! I'll try my best, i might have to start wearing depends though.
the need to hit the restroom every 5 minutes fades after about 2 weeks - then the expression - Peeing like a racehorse - is pretty darn accurate
100 ounces for me yesterday...(about 1 quart low for the day)
