I Have Been Taking Burenorphine, 8mm, 1 1/2 Tablets For

I have been taking Burenorphine, 8mm, 1 1/2 tablets for 3 1/2 years, maybe more now for addiction to morphine. ( self medicated, have gout, bout kinds and bought morphine from a "freind" to combat the pain until he ran out). I am addicted now to Buprenorphine. I have tried to come off it, with no success. Lately, I have been incurring extreme stomach pains across the entire midsection of my body. I don't think it is IBS. When I take a tablet, it goes away. is this a withdrawal symptom? It renders me unable to do anything and is extremely painful. Help! Allington
