33 days into coming off of methadone, and what helped me was immodium, and clonidine for muscle spams and alot of really hot baths and having a strong support system. I cant tell if it is you coming off, or if you are just curious, but I can give you the truth about what happened to me if you want.
There's a few posts here. One is Fladdicts' "Amino Acids" post. The other is one called "The Thomas Recipe", and mine "Methadone Detox: What works, what doesn't"
These should give you a good base of information for what you need. Just use the "search" and put the post title in to look them up. It's all pages of material, so I can't just input it here easily!
There is also another post i wrote called something like Methodone, Nutrirtion and detox... if search that it should come up..
