I've been on Methadone 30mgs for 10 years. I was also on an antidepressant, Xanax, and Buspar. I also used Neurontin for chronic pain. I got fired from my pain management Dr. Because I continued to use the Xanax, after 3 warnings. Then my medical doc dismissed me from his care, saying I was a drug seeker. That was not true. I had called and asked for Xanax with refills, and Buspar. He saw those calls on my chart and jumped to conclusion. Also told me he doesn't prescribe pain meds.
