Menopause is not a disease. So you don't want to jump to the most aggressive response first. Look at your diet, look at exercise, things like stress reduction. Start by looking at lifestyle changes that can reduce symptoms that bother you. If you exercise more than three times a week, you not only improve your overall health but some research shows it decreases hot flashes.
Stress reduction does, too.
There are good data that paced respiration controls hot flashes. You practice taking only five or six breaths a minute. Then, when you feel a hot flash coming on, you slow your breathing down and you can actually stop the hot flash. Nutrition might have some answers, too, based on the observation that Japanese women don't report hot flashes. That may be partly because people there eat a lot of soy protein, and soybeans have plant estrogens that may well be protective.
