I'm taking 2mg Sandrena daily. I'm finding it a pain waiting for the gel to dry, and would like to try patches instead. I've read good things about Estrodot. Could anyone please tell me what the equivalent dose patch would be, to ask for? It comes in 25/50/75/100. My GPs are helpful but not always very clued up on HRT regimes. Google isn't helping! Also, are there still ongoing supply issues with Estrodot? TIA.
