Well misspoppy if he's been taking methadone since August....that's a completly different story. He's probably in denial about the true size of his habit. So I also say there's not a thing you can do. He talks to you so try ask what he's really taking and how much on a typical day. And yes, seek for professional advice, though IMHO sometimes they just manage to make it worse like putting people on a massive dose of Subuxone-
