There was a member posting about alternate-day use a while back. She felt it would be ok but for me, personally, it wouldn't work- I get early-ish bleeding even on 200mgs ( bleed usually by day 9 -10, not 2-3 days after stopping) so I am sure the bleeding would be all over the place on alternate day dose.
Try the vaginal route and see how you feel.
You might need a 75mg patch if you are still getting hot flushes- if you had an early menopause then by now your own oestrogen levels would be very low.This might also account for feeling rubbish- too much progesterone to the amount of oestrogen you are getting.
Fingers crossed for you!
