Hi Liz, I had a hysterectomy many years ago, so don't know about periods. However, having given up HRT on 3 occasions, to see where I was, I'm back on oestrogen again. Flushes & sweats were exhausting. I was hoping the last time I would be able to stick it out, but doctor agreed that quality of life was more important. It's a tough one, but don't feel bad if you have to give in to HRT.
