Sorry to hear this undergroundbarbie. It depends on how far into menopause you were when you started HRT. As you get further into meno oestrogen levels drop so symptoms may return.
If you are on the lower dose ( 1 mg) maybe increase to 2 mg like renee?
Also some women do find they react badly to the norethisterone in the green tablets - but I can't explain why you would suddenly react after feeling OK for the first 9 months?
Maybe if it is definitely only on the green tabs, perhpas it's time to try a different type of HRT. Femoston is one that is generally well tolerated so perhpas try this at the same dose as the Elleste, and also possibly increase the dose later too?
