I'm 32 years old and I've been a smoker of marijuana for the past 10 years. I'm at the stage now where I smoke everyday and without fail I have to have a joint before going to sleep. I've been wanting to give up for the last 2 years and have tried various methods; from gradual reduction to cold turkey and everything in-between. The thing is I still maintain a pretty successful life, as do my close friends who all share this vice, therefore my willpower to completely stop is always compromised by the thought that it the addiction isn really impacting me negatively. Has anyone else been in this position and managed to stop? Can they offer any advice?
