One week today since surgery, (hooray!) I am finding that my internal temperature seems to fluctuate pretty wildly. Sometimes it seems I just can't warm up; other times I wake up in a puddle of sweat or feel like I'm back to having the hot flashes that stopped several years ago for me. My poor husband is having deal with my changing the heat setting up and down multiple times a day. Is this a common problem?

Not uncommon. I had the same thing. Some of it can be anesthesia. It takes our bodies weeks to get rid of all of its effects. Plus, a drastic change in calorie intake can fluctuate blood sugars, not dangerous but annoying.

I had severe diaphoresis (bed soaking night sweats) after the births of each of my children. I understand that this can be caused by anesthesia (epidural or general) and also changing in the hormones, which is caused by a sudden shift in the fluid balance of the body (such as that caused by a sudden weight loss). After the birth of my first child, I weighed 30lbs. MORE the day after he was born than on the day of his birth (a total gain of about 45lbs. Overnight.) because of a slight case of toxemia. They didn't give me anything for it because I was nursing. I sweated it off over the next two weeks a gallon at the time. It was amazing. You could almost hear me slosh when I walked. I hope I never sweat like that again!
