Hi DeeMarie
Like Dotty and Shropshirelass, nausea was very much present when I started on my perimenopause, and got worse as my oestrogen levels dropped. I also had crippling headaches, sometimes 20-25 days a month, where I had to alternate paracetamol/ibuprofen to get relief, and anti-nausea meds. When I finally got started on HRT this improved things for a couple of months (probably because I was feeling SO bad) but once my hormone levels regulated it was evident I needed more. For the last year I have been on a medium dose and symptoms are very much better.
I have recently changed to Evorel Sequi and after a wobbly start, now on month 4 and things are good. I agree, it did feel like hormonal nausea, (i've not had babies so can only imagine what morning sickness must be like). Some days I was off certain foods/drinks. On HRT I do still get the odd day where I feel off.
What I find helps is eating little and often, slow-release/protein rather than sugary things that my body uses up too fast. Exercise helped me too, it stimulates my appetite and getting out in the fresh air is good.
Really hope you feel better soon x
