Am post-meno, taking low-dose E and T daily, cycling P. My body loves the first two only and has bizarre relationship with P, sexually speaking.

I have a rotten time when taking P for 10 days out of the month. It helps me sleep, which is nice, but sometimes makes me startle awake in the night with a sensation of jolts, like I've been suddenly terrified. Other times, I just sleep and sleep. What I don't get is that, for those 10 days, sexual response is goofed up, but after I stop, it's wonderful. Better than the days right before I start using it. This lasts for about a week and then I'm back to usual which is good, then back to progesterone when it's goofed up. So, lousy while on, great immediately after I stop, good in the meantime. I would use it less frequently, but I like this post-Peffect. What's it doing? I figure it has to do with receptors, but don't know what.

Does anyone else have this experience?
