Elsiet, I would make several observations. Firstly, Ellesse contains norethisterone which many women don't get on with because it is a very strong synthetic progesterone with a lot of unpleasant side effects, the type you are having - I can't go near it. Secondly, 1mg is a very low dose of oestrogen and often not very effective for symptom control and thirdly, oral HRT is nowhere near as good as the bio identical, transdermal variety.
I doesn't sound like it's working very well for you so my advice would be to switch to Oestrogel/Utrogestan. I have found this to be the most effective HRT regime by far and would recommend it. One point I would make is to limit the use of Utrogestan (micronised progesterone) as much as you possibly can because this can also have side effects if used in high doses. There is much debate on here about how much you should use but a lot of women are now switching to using 100mg Utrogestan vaginally for 7 days each month - Professor Studd's prescribed dose. The NHS will try to get you to take more of it but I found I didn't need anything like the amount they suggest which I think is about 100mg for 12 days each month - completely out of the question for me.
As you have been taking only 1mg of oestrogen orally, you will probably find that 2 pumps of gel each day would be enough.
In order to adopt this regime and know whether or not the Utrogestan is doing its job, you can have a womb scan to check that the lining is clearing properly but you don't have to worry about that until you have been using it for a few months. The thing is, you can't guess how much Utrogestan (or synthetic progesterone) you need and every woman needs a different amount.
Hope that helps.
