... oxy. My heroin habit has gotten out of control, almost 3 bundles a day. I am desperate to get off it. Usually I can get methadone and I get off without a problem. But I am having trouble getting methadone. The past few times I have tried to use suboxone it hasn't worked for me, hasn't stopped the withdrawals. Is this because my habit is too big? Would subutex work better? I am just desperate and looking for one last chance. :(
