Hello and welcome to the forum~
We have a lot of members who have successfully weaned off of Methadone.....do you have a plan already? How much lower you will taper?
There are a lot of things you can read to help you during this time...even just typing "withdrawing from methadone" in the search box on this forum will give you lots of previous threads to read that will give you really good information. The reading will help in more ways that one :)
If you haven't added some extra nutrition to your daily routine yet, it would help you a lot. Amino Acid shakes of some kind, Emergen-C and for sure a Cal/Mag/Zinc supplement twice a day. Here's a couple of links that may help give you some more ideas:

Please keep posting...ask anything you want to....we're all in this together regardless of our DOC (drug of choice).
