I had been using opiods for about 2 yrs (this time) averaging 400-600 mg per day. I haver safely switched to suboxone for a personal reason, although they work fine and In take aboput 4 mg about 5 days a week. A friend suggested I go on 75 MCG fentanyl patches for about 2 weeks and if needed a little bit of sub for a week. Main question am I still opiod tolerant and has anybody ever heard of this working before. My friend states he got the idea from a docto (addicxtion specialist) I would appreciate and input.   thanks    Nick.
