My drug of choice is beer but all addictions are similar. Lookup NA and drive by the place, if someone is there go talk to them. If not then you will know the route. Summon what courage/fear you have and go to the next meeting. Force yourself. You have to make the effort NOW not tomorrow. I put off quitting doing about my drinking a day or two, then I'd feel better and drink again. I go to jail on the weekends but finally decided to stop drinking-you'd be suprized the things that have a "silver lining"
Sober is right. I quit many times over 30 years. The last time has stuck. I was desperate and will to do anything. I drove myself to AA and walked in, not an easy thing for me.
