Most doctors told me I had to be down to 20-30mgs methadone to switch, that would have taken a year or more, but I found a doctor who actually knew how methadone
and subs work and why, greedy as he was, he saved my life
. Being bipolar 1, a year of tapering was a simple impossibility, so I am glad I found a smart doctor who could help me. I suggest that to anyone, go to as many doctors as you have to, but find one who knows what they are talking about.
