I have been having hot flushes since March 2009 when I was a the end of my chemotherapy. I had them 24/7 every 2 hours. I could set my clock by them. Thankfully over time they have decreased and now I can get 3 to 4 hours sleep a night then the hot flushes kick in about every hour or so. I think I have just adjusted to disturbed sleep but it does get frustrating to be woken with hot flushes. I chose not to take anything as my breast cancer was highly oestrogen receptive and all natural products contain some oestrogen. As for prescribed medication, I am only on Femara. I think the less you take the better of you are. I hope that the flushes will lessen in time. My only wish is to stay well and be free of cancer.
