your doctor probably won't let you take those hormones for more than 2 years, then you're going to go through the same thing again!
a friend of mine prolonged the agony for years by getting on and off hormones.
I am 56 and have been in full menopause for 3 years and I still get hot flashes day and night. The frequency is finally going down but i still get some doozies.

I find them somewhat amusing, because I'm usually cold. good luck.
