My boyfriend is 21 years old and he used oxycotin for about a year and a half....he did at least 7 80's a day....He then deceided to go to the methadone clinic and he was up to 120mg..he relapsed and he pissed dirty and they kicked him out of the clinic...he knew he missed up so he transfered to the Indiana Clinic and from there he was stable on 80mg for about 2 months. He couldnt afford to drive up there every day, so he decided to quit cold turkey.....Hes on his 4th day today and hanst been throwing up, or had the runs. He says hes been sweating and describes to me that all his bones ache and constatly feels like hes fieining for a cigerate and has headaches. How long will it take until the worst part comes? And do you think he can do it cold turkey??? He hasnt eaten much and cant sleep hardly at night.......PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
