 How long do the hot flashes last? I mean, is it just a flash or is it something that's... I have no idea. It's kind of like summer. It's really summer. I had hot flashes, I mean, I don't now, but I've had it for like a year or two, but to me they aren't that big of a deal compared to what I went through when I was having periods. But it's just you get hot for a little bit and then you get cooler and you just have to keep taking your sweater off and on or you have to take your blanket off the bed and then back on all night long. That's all it is. I don't think it's that big of a deal, frankly. Well, some women become drenched and actually change their clothing 10, 20 times a day because they are so drenched. And those women also have hot flashes for 10 to 20% of them for the rest of their life and they do stay on long-term estrogen as a result.
