Anyone on Estrogel for more than a couple months?

I have been fiddling with Divigel and Estrogel for about three months, trying to find the right dose and application, because I had to quit patches and doctors didn't know much about gels. I finally settled down with Estrogel and applied consistently once a day.

I tracked my symptoms everyday. The first week or two were very inconsistent and I had many symptoms. After two weeks hot flashes were mostly gone but I still had headache. Four weeks, joint pain was much better but boobs were sore. Six weeks, sleep is better, higher quality but still not long enough. Do I dare to hope for more improvements? Nothing has touched brain fog yet. Did I feel better gradually because estrogen is building up to a higher level, or my body is getting used to it? Those of you who used gel for longer, how long did it take for it to improve brain fog? Vaginal dryness? Getting 7 hours of sleep?
