I have been using methadone for pain management but have been unconscious most of that time. I went through withdrawal this weekend but still need something for pain including headaches that have sent me to the emergency room in the past. There must be a non opioid, non addicting pain killer that comes close to the pain relief of methadone and fenynal. If you know what it is tell me now. I refuse to take a methadone but the pain is about to win.
