I prefer injections for many reasons, one of them being that I don't like to have to remember to take my E pills, nor why...
But my endo has me taking 2/3rds of my E in the morning, and 1/3 at night. My understanding is that after a while one builds up a consistent blood level, and that it may lower a bit between dosages, but never back down to zero.
When I was pre-op and on spiro, I took one at a time through out the day, otherwise it made me dizzy. I was on a lot so it seemed like I was popping a pill every 4 hours, ha ha!
Sometimes I do wake up early on my own, and WANT to take my E, even now, lol. I looooves me some estrogen, oh my, yeessss!!! Good stuff, mmhmm...
