Yep. I was a total alcoholic, then stopped...then got addicted to pain pills...then stopped. Then got addicted to benzos. Stopped mostly but my shrink gives me a small amount every once in a while. He is aware of my history. My self medicating and being dishonest about my symptoms and drug use in the past made it so I was never properly diagnose until I went completely off the rails last year. Now I still smoke pot. Definitely self medicating, but the pot works better than everything else and it helps me stay away from the hard stuff. Some people call it the 'marijuana maintenance' program.
