I have been taking methadone for 5-6 years for chronic pain due to cancer. my highest dose was 240mg and I was pain free. because of the increasing difficulty at the pharmacy I had a Pallitive. care doctor who is transition me from methadone to Suboxone. I have lowered the dose of M over the last month now at 3 tab TID (IOmg) transitions to Suboxone sublingual tab (buprenorphine 2mg and nalaxone .5mg) increasing daily. however I am having withdrawal sx that are awful.
