Addiction?

I have been smoking weed for 5 years now, recently I have been re evaluating my situation and I feel now is the time to give up my vices. I have dealt with hell these past 5 years and I used weed as an outlet, it was always the thing that I could just do and any problem would melt away....for a while that is. I steadily smoked my way through high school and now most of college and I am ready to quit. But heres the problem, I have been a daily smoker for 5 years...quitting just like that is impossible believe me I have tried, every time I get a little weak or upset thats what I turn to. I would like to quit naturally and over a small amount of time without rehab, any suggestions?

THANKS EVERYONE.
