Judith, I've taken both Provera and Prometrium and from a personal perspective i would say that differences have been quite subjective. I haven't had any particular physical changes with either, i think my face has got more feminine with Prometrium, but that also could just be that i have been on hormones for about 16 months so some changes are likely.
I seem to be sleeping better since I have been on Prometrium, and generally i feel better, but as i say, that is quite subjective.
