Just to add to what these guys said... when I was feeling almost the same way you were like end of last year, I quit for up to a month.... NO DRINKING-NO SMOKING....it kinda sucked, but honestly I felt addicted, and I felt that weed was sucking me in and making me isolated from the rest of the world and esp. my friends and family, and I was only doing it at this point about 1-2 times a week...

well, to continue with my results, I found out awhole lot about myself and weed, and how I did notice a large difference in my outlook on life, and think I concluded that my new and positive sober outlook was in many was due to smokeing weed and experiencing different states of mind.... In my oppinion weed helped me become more mature about things, and has ultimetly helped my find out new things anout myself and allowed me to figure out what i want in life.... and that was just happiness, and less stress, and weed helped give me that...

Now, it is about 6 months later and I have been smoking just about everyday since I started back after my 1 month break, and Im feeling better than ever... I am almost always happy and I feel I havn't been closer with friends and family.... my best advice, like they said up above is to just try this out for yourself and figure out what YOU want...
