I am 51 and had hot flushes start in January. They ramped up pretty quickly to ~10 a day and were very embarrassing and frustrating. I'd go bright red and then profusely sweat, people would wonder what was wrong with me. By mid Feb I also hadn't had a period for 4 months and was beside myself (not sleeping either because of them!). I had some left over powder from trying Happy Hormones a couple of years ago and started that again, and within 2 weeks the hot flushes stopped! I even had a period, which I take as a positive health wise. Every now and again I feel a mini sensation of a hot flush, but its really nothing compared to before, and usually if I forget to take HH for a day or 2. I'm now taking the HH capsules which while having to swallow 4 tablets, it is easier than the powder.
