I am glad you are moving out too!!
You will find a lot of support and information on the Substance Abuse boards too, specifically about opiates and folks who've beat the monster. I have been clean from alcohol, opiates and about anything/everything else i could get my hands on for a little over a year now and it was the hardest, but best thing I have ever done in my life.
Your doctor is best to chat with about a specific detox plan, but if you've been clean for a few days, that's a wonderful thing!
I also had to change who I thought were my 'friends' and most everything else in my life to get and stay sober.. it's a new and wonderful life, and it sounds like that's your direction too, if you choose!!
