These Estrogen Blockers have lots of symptoms - not everyone will have them all. But basically, if you remember how you felt during your menopause, you may be going through similar symptoms again, because menopause is when most of your Estrogen goes out of your system. After that you have some Estrogen left in your body and the Estrogen Blocker is now blocking what's left. Or almost all. Hence, all the hot flashes etc. I would check with your doctor to see if one of the other two Estrogen Blockers would work better for you. Also, ask your doctor if you can take a two week break from the pills - some people did this to give their body a break! I think you might need a break to relax and raise your spirits. And remember, nothing lasts forever. Things will get better.
