I'm on methadone and Xanax, changing doctors this month... I actually quit the methadone for a bit; then, required another surgery and got back on it. Anyway, that's kinda what it sounds like. I went cold turkey, felt like I was dying (kinda wanted to). I was hot then cold, restless but tired, sometimes a bit disoriented, agitated at times, etc... I went to Health Hut, & was totally upfront about it, the girl gave me a few things for the stress and tension.
