I have had hot flashes
for about 4 years now. I have had only 3 periods
in that time. Until 6 months ago, the flashes were dry and as normal as a hot flash can be, I guess. But since then, I get drenching hot flashes and night sweats, but before they come on, I feel really nauseated, my heart feels like it is going really fast, my head pounds, and I get overall REALLY sick feeling. I am having about 5 a day and 3 or 4 at night, which wake me before they happen.
