As per buddism, how is it possible to leave behind my obsession with drugs?

I don't want to consult any doctor about my obsession. I do not even want to speak about it to my family and friends. I wish to get an answer tailor-made for me about my obsession with getting dead-drunk and practicing self, the meditation. Please don't take it otherwise but a question to Buddha & his disciples. I am so fed up of the dependence of me on drugs. It happens, believe me (i have seen many others, too). Please provide/mark/show/point wordings of Buddha if he has said something near to this. If any modern Buddha is reading this than please share actual revert of you with example. I am standing at a dead-end (may be here's some way ahead but my thought isn't going beyond my confusion. My philosophy about buddhism says that it's a way of living that is worth living. I am practicing meditation in routine in early morning timings. The rest of the day i depend on drugs to stay connected to the will of mine to become a Buddha, it appears like a bridge that i can walk and i walk across it, everytime. *How is it possible to leave behind my obsession with drugs?* I want to quit my drugs. I wish to be free.
