Personally, I was happy to have started off on estrogen only - for the same reason that my doctor recommended it, that, like Cindy, I never ended up needing anything else. I hate taking medication, so being able to avoid taking a second drug was an advantage. Not to mention that I have a terrible memory, so getting estrogen by patch that I have to remember to do only twice a week versus two different medications, one a twice-daily dose, that have to be taken more or less independently and at different times... 🙂
