I have been on methadone for 8yrs. I weened from 55 mls while pregnant, average of 3 mls/wk. After two years of being off, I was in so much physical, I went back on it. My dose has been 15mls/day for a couple of years. I experience so much pain when I try and stop.Before painkillers. I would get a mild pain in my tailbone bome sometimes but don't remember experiencimg much physical pain growing up. I'm 43 years old and when I'm am lower than 10mls, it's so painful I don't know what to do.
