I just had two nights in a row where I didn't sweat, and I slept kinda well, helped by Melotonin (well, Melotonin AND Unisom last night). I'm not as intolerant of the cold as I have been--not by far.
I am still taking hydro, but just one 5mg a day. I feel like the Tramadol-unique withdrawal symptoms are abating and it's getting close to time to jump off the hydro.
Pretty exciting!
