I have found it can go either way with me if I'm not vigilant. Toking does tend to give me the munchies, BUT, if I pay attention to that urge instead of reflexively pouring a bowl of chocolate Lucky Charms, I can make it work for me. I can get lost in a long train of thought about how awesome it feels to be small and trim and how no calorie bomb is worth jeopardizing that and before I know it, I'm totally motivated to ignore the munchies. I was going to say that that never works when I get the munchies sober, but then I realized that I never get the munchies unless I've toked, so the fact that pot can help solve the problem it caused in the first place is starting to give me the same kind of eye twitch that reading fat logic does.
