Juuust quickly like that. Sounds like part of your trouble might be unstable levels throughout the day. It's more expensive, but I'd still tend to advise that you try a transdermal gel. I had a very small part of your symptoms (very small dose, so) when I was on Estrace, and even though it looks like my dose might have been actually reduced in the process (gotta love very available endos - still waiting for an appointment), when I was switched over to Estrogel, they disappeared, poof. They were actually caused by the "down" of E at the end of the day.
I would suggest talking to your doctor about replacing part of your pills with Estrogel. Maybe even just one shot per day (which is probably roughly 35 $ per two months, not so terrible). It'd add one steady, stable element to your hormone regimen to smooth the up-and-down curves. It might be all you need.
