As stress for me is the main reason for hot flushes, followed by caffeine and alcohol, my way to best cope has been to start mindfulness meditation and now that I'm getter more into this I really feel my stress is less and more managable. This plus cutting out caffeine and alcohol (when I can drum up the required will power that is) seems to work. I'm 70 and have hot flushes every 45 minutes and nightsweats. I didn't want to go the HRT route but at long last gave in..was beginning to feel like a blimming martyr!.. and saw my gp for a prescription. However I was told I had missed my 'slot' and to start taking HRT now would be dangerous. In short, went to menopause clinic, the dr there specialized in menopausal problems obviously, she agreed with my gp, so got put on clonidine which has somewhat reduced the frequency.
Just hoping this book has some hints on surviving hot flushes in my 70s and beyond. Dream on....
