I had terrible hot flushes at first. Well, I say at first, they probably lasted about 5 months quite severely. And another few months sporadically.
I found some articles which helped a little, but definitely helped me understand the condition much better.
Here they are: www.changeoflife.co.uk/menopause-hot-flushes-flashes
Another good source of articles was over at www.menopause.org
I think both of them are charities or non-profit. I think the second one might be some government site. I'm not sure.
But they did have lots of useful info.
Hope it helps.
