Green Tea, Bro =) Not only is it hella good for you, it's got a good amount of caffeine and natural substances to clear your head up and keep you going it; it's great shit. If you REALLY wana clear up fast, I've noticed Salvia knocks off a lot of the lazy, zombie-brain feeling you get after smoking. I wouldn't have believed it if I hadn't tried it myself.

Course, I always advocate that people take good weed breaks as well. I usually stop for about two weeks to a month after I've finished off a sac and then buy some more. Love getting blazed when I haven't had any for a long time.
