anyone got fibromyalgia on MMT?

Wondering about something to take for this stinking fibromyalgia? I am on 120 mg of methadone.  Seems like the lyrica, cymbalta, prozac, elavil did not help me at all. I also have hep c so I have to watch what I take because it may be hard on my liver as well. My doc at the clinic will not raise me on the meth and the pain doctor will not help me because I am on methadone. I get so uncomfortable sometimes and it is rough. I see it will be hard in old age on this stuff, but of course we never realized the nightmare it would be getting off of when we started this journey! Feedback appreciated!
