I started having hot flashes when I was 47. They are relentless. It is so disconcerting when, in the middle of a business meeting, that prickly feeling on the back of my neck commences. Beads of sweat gather on my forehead and upper lip. I know my face must be flushed and shiny. I’ve tried a variety of homeopathic and pharmaceutical remedies, all, basically, to no avail.
