I also was tired of pot taking control of my life. Funny thing was, I was never addicted. I just, always felt like doing it. I smoked everyday (at least 3 grams) for 6 years. I worshipped the stuff. But it got to the point where it wasn't fun for me anymore.
On New Years Eve 2007, I thought to myself (while smoking pot), I think I'm going to see if I can quit smoking this stuff. So, after midnight, when everyone started lighting up, I didn't participate. I had a really bad cough at the time, and by not smoking pot I saw a HUGE difference in recovery time. Now, 1 year later, I haven't gotten a cough once. I even smoke cigarettes still, and have tried to quit them MANY, MANY times, but, to no avail.
I think at least limiting yourself with your pot use will be very beneficial to your health. And when I say limited, I'm not thinking once a week. I'm thinking 2-3 times a year.
I will tell you this. I visited some friends who smoke pot when I was about 8 months pot-free. I gave in to the temptation, and smoked while I was there. I suffered from EXTREME depression after that. I mean, my brain didn't seem to work right and it took me about a week after that to get back on track.
Very strange thing to happen to an ex-pothead.
