Hi again prestige
Firstly, if you felt unwell on both the iestegn and the combine oestrogen/progesterone part of HRT, either you are super sensitive to any hormones (which would be very rare) or there is something else going on - maybe an allergy to the fillers in the HRT. Unfortunately it is not uncommon to develop allergies and extra sensitivy to all sorts of things when meno hits. If you were already feeling unwell and nauseous before for you started HRT, taking HRT orally might not have helped.
Are you still peri meno? Do you still get the occasional bleed? How old are you?
You were put in a sequential HRT so I am assuming you are peri meno, so your hormones may well be fluctuating so the fact that your Night sweats have stopped could be because you oestrogen levels have gone up again for a while.
The other thing that should be checked is your thyroid function - perhaps ask for another blood test to look at thyroid, FSH and oestrogen levels.
As to what happens after menopause - I'm sorry to tell you that, even when flushes and night sweats subside, the lack of oestrogen can continue to cause deterioration of urogenital issues, joints, skin etc. Essentially oestrogen helps to maintain many things and without it our bodies will suffer. I believe many will find a more balanced way forward once the body settles over the approx 2-7 years of the menopause journey but for some, meno symptoms never truly go away. Being post menopausal is a permenant state of being and bottom line, it is all part of the aging process. How badly this lack of oestrogen effects each of us will vary greatly - after all around 40% of women sail through with few, if any, problems.
This is why HRT alone is simply not enough - we have to adjust our life style to compensate for this lack of oestrogen.
