After two yrs on MMT my legs swelled up. Open sores are festering Wound care almost healed them Fluid is now weeping like sweat from my leg. My doctor shouted at me,"I don't know what causing this. I've looked at everything it could be and your are fine." I can fall asleep and dream standing up at the grocery store, at a red light or washing dishes. I certainly do FALL asleep and I am alarmed when I hit the ground. Am I sweating from Methadone or experiencing hot flashes? I am full blown AIDS and HCV positive w/no viral load. I'm clean 3yrs with the help of large dose w/no craving 240mg daily
