Hollywood, Trust me I never thought I would pull "crackhead" moves and sell **** either. I come from a very rich family, I lived in a nice house, I always made good grades. I think your deluding yourself if you think you can do this alone. Unfortunately willpower is not the answer. I have tons of it and plenty of others here do as well. Addiction is a very tricky disease. But...if you do it on your own kudos to you. If you don't succeed i'd strongly recommend a rehab, even outpatient.
