I was on HRT for about 18m. I asked for it because of brain fog and lack of focus. I dont think it made much difference for that, but it did stop the 4am waking, which I didn't realise was a menopause symptom.
However, the progesterone gave me horrendous "PMT" symptoms, real red mist rages. GP switched me to continuous progesterone, but that just meant I felt on edge and prone to rage every day rather than a few days a month.
So I've stopped. I feel much better but and sleeping terribly and getting lots of flushes at night, which I wasn't getting before.
I'm taking magnesium, but it doesn't seem to be helping as yet.
