I’ve been taking methadone because I was in cancer treatments and was prescribed OxyContin 40mg 3x daily , well after almost a year of taking the OxyContin, my cancer treatments were successful, which I’m very glad of, but the doctor just stopped giving me the OxyContin, which led to horrible detox tremors and extreme flu like symptoms, so I had a guy give me heroine, I never injected it, I only snorted it, but I found out very quickly that I could not live like that either, so after about 4 months of sniffing heroine, I got into a methadone maintenance program, and I’ve been clean and sober since day one of the program, that was May 9th 2009. This coming May 9th 2019 will be 10 years. But I’ve been fighting severe constipation for almost 2 years now, and it’s now to the point where I will go about 2weeks without having a bowel movement, then all of a sudden, I’ll have Diarrhea for like a week, but nothing but brown liquid comes out. I’m afraid that I may be getting toxic to myself, because now I also have body pains and my hands and feet are swelling up too, and it’s so bad that I can not even get out of the bed most days, it’s ruining my life. But if I stop the methadone, I’m afraid I’ll go back to the heroine. What should I do????????????????
