Your symptoms sound similar to what I have been experiencing. I could handle the hot flashes and other minor discomforts, but the migraines and palpitations with a racing heart really got to me. At first I didn't realize that it was anxiety. BUt my doctor did. We tried Sarafem(prozac), but i had a blood pressure reaction to it. Now, am on Celexa with good response. Every now and then I get a bit flaky when my period is due, but it is not as bad. WE also tried verapamil for my palpitations, and it has helped with the length and intensity of the my migraines. Some of the heart drugs,like verapamil, are helpful with the migraines. Ask you doctor about them.
