I'm having TAC and have found the hot flushes at night unbearable as my head is constantly wet and have tried just about everything, ice even bought a chillow which is basically a very cold pillow! Nothing I did or bought helped. However, I was thinking about it scientifically the other day, and because I'm always hot and sweating due to the flushes I never wear anything on my head, but when I was thinking about it I thought maybe some of the problem is the heat from my head hitting the cold air, especially during the night when the tempreture drops. So I decided to wear a sleep cap to see if this helped and it has! Finally I sleep almost a full night. Just a thought?
