I smoke once or twice a week, one bowl only. So I would not consider myself a heavy user.
However, after about 2-3 weeks of not smokeing, I start really getting well down in the dumps. Honestly, mood swings, just feeling like life sucks..... Just odd stuff, example finding a dead bird is enough to make me cry. Normally, that doesn't happen.
I'm pretty sure, that my past XTC had something to do with all this. I don't do X anymore, been about 2 years but if I don't smoke pot for a week or so, well it's almost like that "morning after" feeling you get after a good night out rollen.
So, I havn't quit. Now, my use doesn't affect me otherwise. I have a good job, I pay my bills, etc..etc. All I can say is, it helps me stay "Balanced"
