Hi alibabs1965
As well as considering Dotty's suggestion, alternatively you could ask for Evorel 50 patches (which is the oestrogen dose and type of patch you are used to) and try a separate progestogen. utrogestan is one, and the other is the synthetic Provera. In your position personally I would do the latter (ie stay with Evorel and try a different prog) rather than change two things ie from patch to gel and also the progestogen) - only in that you will know by only changing one thing whether it is the progestogen ( in the Evorel conti) that was not agreeing with you!
