@Lia73 Going right back to your original post I'm not sure what you want to know.
This thread has developed into the (usual!) 'argument' around HRT.
For you personally, if you have symptoms that are causing your quality of life to suffer (ie you can't sleep, you can't work so well, you have low mood that's overwhelming etc) then you could try HRT.
We're all different. Some women get 1 flush a day, which they cope with, some get one flush or more an hour, as well as night sweats, and they can last for decades.
If, at the same time, you have a higher risk of osteoporosis, or there is heart disease in the family, you will gain some benefit from HRT too.
You can't be prescribed HRT as prevention for anything (especially wrinkles!) but if you are at risk of osteoporosis, or have got severe osteopenia already, HRT is a prescribed treatment for women under 60 rather than other drugs.
