Methadone
"I have been on Methadose for about 10 years.  When I started treatment I soon learned the good and bad sides of methadone maintenance treatment (MMT). Yes, I have my life back, I am clean and sober...but methadone is a double edged knife. I have tried to detox from it, I cannot begin to tell you the pain of detox, it's the worst detox I've ever had. It took me 1 year to feel normal! I've gained a TON of weight from methadone. I don't know if methadone causes you to gain weight, but I know many people that have gained 25-50 pounds after starting methadone. Also, my teeth are very bad. I need dentures,  I'm not sure if methadone was the cause of my bad teeth, but I know many people with the same problem. I would tell people think about MMT before starting it."
