Methadose and couch

So far for me, methadose has been helpful as far as my addiction to heroin goes. I have had a lot of days that I feel tired but I've found if I keep myself active and busy that feeling does not happen until I let myself get comfortable on the couch in front of the t.v. or lay down in bed, then I am OUT. But all and all, I've had no bad side effects and have been on it for 2 months now at 100 mg a day. I have gained a few pounds but nothing horrible or that I can't lose.

extreme tiredness, loss of appetite, dizziness, panic attacks, fall asleep sitting up..start to fall out of chairs, off couch, out of bed
