Do I like hot flashes waking me up at 4 am?

That would be a NO.

I didn't think surgical menopause would be a lot of fun, and years of autoimmuning have certainly raised my pain and suffering threshold. So hot flashes are not the end of the world. But mine seem to be on the severe side (can my body do ANYTHING mildly?) and I am going to be pretty pissed off if they don't at least burn some calories.
