Hey rxtweeter. I too have an impulse control disorder, and that's what led me to addiction problems. I very rarely had physical withdrawal when I was quitting because the harder part for me was going through the motions. I never went to a 12 step program in my life, so I can't speak to that, but maybe find other places in your life that your impulse control disorder is affecting (for me I bite my tongue and sometimes other people (like my fiancé… poor guy's got scars) or myself) so you can go to the doctors and say "this feels the same as doing drugs, and if I stop doing this it gives me the same anxiety as not doing drugs."

At least, that's what I would do. I never told my doctors about drug problems, I have a friend who helps me cope with that.
