I used 40mg-80 mg oxycontin for about 6 months, and then 2-4 bag a day sniffing habit of herion for another 6 months. I went on short term maintence for 4 months. I was on 55mg for 3 months and I am not on 45mg. Starting Oct 8th, I am going down 2mg a down, and will be off by November. I am worried about the withdrawl, has any experienced methadone withdrawl and was it tough for you? Also most importantly, I worried that my herion cravings are going to come as intense as they used to be, and that scares me since I been so stable without cravings the last 4 months. Thanks for listening.
