Hi Crispy,
Unfortunately the symptoms, which are appeared due to reproductive years are going to the end, not really are going to respond to any other treatments apart from hormonal therapy. I did manage to control hot flashes and night sweats with sage in my 40s, which were caused by low progesterone, but the same sage product didn’t help me in post meno, when the same symptoms were caused by low estrogen, it also stopped working for me at the end of peri, when I started bleeding heavily.
Nausea and motion sickness came with post meno stage, so I would suggest the symptoms were caused by mix of low progesterone and low estrogen the same time, they ended up on the bottom in a strange for my body proportion, yes and I should mention it, I still had a good level of testosterone left in my body. I suggest because I have highly sensitive to sex hormones body it made things more noticeable for me.
After trying body identical HRT for a year I had to give it up, because it obviously made all my things worse. I am currently on Tibolone, have started taking it 1.5 months ago and this is the only type of treatment, which really works for me. If you want to shut down your hormonal reproductive system at all, do try Tibolone, it is really worth it.
