First , id like to say hello and god bless to all , ive been suffering w/lower back pain from a murdercycle in 1989. Does anybody else use methadone for pain relief, I do 20mgx2a day. Ive found it to be the most reliable pain med yet , I have not even needed a increase in 4 yrs. Anybody else who uses , could you please let me know of any log term side effects, my wife says im very forgetful. Your help would be greatly appreciated ...Thanxs in advance -lets try to stay strong
