"i have been on methadone since 1998 and it&#039;s the best pain reliever on the market today. i have been prescribed almost everything for my pain and nothing would touch it. it might have taken the pain away for a short period of time, then i would have to take another pill. methadone is unique because it has what the doctors call a (half life), this means when you take methadone it doesn&#039;t (peak) out in 2-4 hours, it last the whole day. like other pain pills such as oxycontin, vicodin, demerol, or any other opiate, they peak out at about 2-4 hours. in the last ten plus years i have been taking methadone, i have been able to function, do normal day to day operations, and even maintain a full-time job. methadone is the best pain pill out there."
