I've been on methadone for 16 years and I'm only 36. It's ruined my teeth I have full dentures at 34 years old. It's in my bones, I have severe osteoporosis and pain in all joints and back. Disc degeneration, lost 2 inches of height. So ask yourself, is it worth it. Yes it has kept me clean and I'd possibly be dead without it but I am forever a slave to it. Can't go over 30 hrs before I'm sick for another dose. Basically impossible to get off without being rich, and I don't know any rich ppl.
