After 15 years of being maintained on a 95mg dose of Methadone for Heroin addiction, I'd had enough. I dropped 10mg off the top, then lowered my dose by 1mg per week until I reached 50mg. At that point I slowed down (on advice of my counselor - not because I was feeling any sort of withdrawal affects) and began going down 1mg every TWO weeks. Took about two years. Until I dipped below 20mg, I didn't experience any withdrawal symptoms AT ALL. For the last 20mg, I had a slightly runny nose, occasional gooseflesh, and in the last 10mg I had a little trouble getting sound sleep. Now, three months after that last mg drop to zero, I'm sleeping normally again, no drippy nose - NOTHING. It's like it never happened. Except that it took 15 years for me to get the courage to try, given all of the horror stories and scaremongering. It IS possible!
