Add to that list, taking maybe 2 shits a week...maybe, and lots of weight gain. Amongst other things...
And add to that, not being told any of these things, or the truth, in general, by any of the "doctors" at your clinic. They don't want you to actually get off methadone...EVER... that's how they make money. Don't you get it, man?
BTW, also something nobody will have the decency to tell you... In that picture of yours, you look like total shit, bro.
