The problem with buprenorphine, whether it's pure, in suboxone, or whatever, is that it's only a PARTIAL opoid agonist. That means that it is limited in its effect. Based on the years of research they did with the stuf before it got approvedf, if you're using over 40mg of methadone, it's real unlikely that any ampunt of buprenorphine is going to keep you out of withdrawal.
