I've been on methadone for about 25 years.
Was put on it by Dr. S.' psychiatrist/pain specialist.
I was told to think of it as "blood pressure medication", as I'd probably be on it for life.

I've been from 10 to 100 mg, through the years (up at second accident), now, I take between 50-60 mg / day. Along with 30-60 mg Cymbalta, some diazepam, and occasional maigraine meds. (I know I'm forgetting something), oh, some lidoderm patches, cut in three, for my back/neck.

Methadone works well, but as even with Tylenol, (which will destroy your kidneys/liver), Respect it!

I wish you the best Finz!
(Is that a Buffett thing?)
