I can relate. I quit oxy's a couple years ago and went through the sweating. Also a load of other symptoms. And yes, I'd live in the bathtub basically. Went from hot to cold... restless legs at night.... stomach discomfort... anxiety... insomnia. 14 hours isn't very long. Be prepared for it to get worse for a few days, then level off and start to get better. 60mg for a few months will be hard, but it gets much much much worse the longer and more you do them.
The best thing to do is try to eat well, and get any exercise you can. It's hard. And avoid cheese. I learned that the hard way.
