Sorry to hear about the side effects from Zoely - but do remember that any treatment is going to take a while to settle and for your body to acclimatise - most - even bio-identical oestrogen preparations - will cause some side effects and bodily changes. However I know that some women cannot tolerate any tablet HRT due to stomach problems - and I'm not sure whether these settle - I've never taken oral HRT and took the pill 40 years ago for about a year, so can't comment!
However you should be able to find some form/dose of transdermal HRT that does help, hopefully?
