Mine was mostly mild, maybe on the medium side. I started having symptoms in my early forties, actually late thirties! My periods got heavier and more irregular, until finally, around age 45-46, I had a couple of occasions of seriously heavy bleeding when I was out of the house, which was scary for me.
I gained some of weight during this time. Then I started cycling. I had 2 years where I went for 10-11 months without a period, and then I had one. That sucked. They finally stopped when I was 48. For the first year, I had no symptoms at all. Then I started getting flashes, but more like what Shooting Star describes. Always first thing when I woke up. I would get them a few times during the day, mostly in the AM, and not lasting very long. I just drank a lot of water to deal with it. My classroom was very warm and I had to make sure I wasn't overdressed for that. It seems like being in a warm environment made it worse. The flashes lasted for a couple of years, then went away, until I started taking medication that made them come back. I no longer take that medication, so no more flashes.
The worst symptom I've had is the dryness, which has been solved with using the E-string. It was severely affecting my riding when I first got a road bike, but thankfully, my doctor is a triathlete and she knew how important it was for me to be comfortable (not to mention how this problems affects the love life).
