HRT is suppose to make you feel better!
Sometimes I don't think the trade off is always a good thing, continually searching for the right HRT after so long, maybe your body is trying to tell you something.
In most women flushes eventually calm down, VA can be handled naturally or with local estriol or estrodiol, maybe subjecting our bodies to larger amounts of hormones post menopause can be too much for some women.
I am certainly glad not to have migraine type headaches anymore and my body does not feel controlled anymore by hormone ups and downs.
I don't have the answers for you Anjia, the only thing you can do is come off hormones and see how your body copes.
