I get horrible hot sweats at night while sleeping. After about a day from not having any drugs in my system (methadone, oxycotton). Its horrible, like soaking wet, sweating all over. Is this common? im trying to wean down, from 15mg a day of methadone.. used to be higher. I was major in oxycotton before and methadone actually helps me focus and not withdraw. If i can wean down to 10mg, then cold turkey, how long would with draws last? a week?
