Methadone
"I have not been on Methadone for a great amount of time but i have been on it long enough to find that the pain free result IS NOT worth the life ruining effects its having on me. I have NO life because of this drug. It makes me so tired, lethargic and just useless!! I can't work anymore, I can't maintain most social relationships anymore, and I am so isolated and lonely now which is having serious deteriorating effects on my mental health condition!!! I have never hated another drug more than this one. 
I know that for some ppl... it has changed their lives for the better and I'm really happy for these ppl!! I just think that people need to know that there is a real nasty side to methadone too for some of us. Cheers."
