Hi,
I know a little about pain pill addiction, 1) I take them, and 2) I was in a relationship w/ someone that had a 4 year/ 15+ per day addiction to Vicodin. She tried so many times to quit but could not and ultimately went into a methadone clinic. For some extreme cases that is the best answer, however, it is BY NO MEANS an end to addiction because most people that go on it end up having to stay on it for life (as a maintenance drug) because it is sooooo hard to get off it. So I would not recoment that route. The clinics make you go thru so much BS, basically they have you over a barrel, you can't miss doses of that stuff. The only positive is you only take it once per day. The negative is form most it is a lifelong commitment, quite a hefty ball and chain.
Anyway, I have been to alot of forums about pain pill addiction. Pain pill addiction is a bit more than other addictions because they cause a chemical change in the brain and it in most cases it is not just a matter of saying "OK I'm qutiing this stuff" and then going cold turkey. It is a battle on all fronts - mental and physical and I don't know which is worse. Outside professional, medical help is a good idea. At one forum someone posted a recipe of a few combination of (non-addictive) drugs that help with the physical withdrawal. As for the mental, your best defense is to first truely hate the stuff (it will be that much harder to quit if you like it). Also, throw yourself into other things that can keep your mind busy. Talking to people going thru it also helps. Here is another forum I like:
