I'm unable to take HRT, Stage 4 br ca, with hourly, no kidding, heart stopping hot flushes. All day, all nite. For 20+ yes now. When I take 3x daily Flagyl they 100% disappear! Why? I want desperately a similar non hazardous alternative. Nothing has worked. Low dose daily did not work. HELP! It's a miracle and I finally got sleep!
