My hot flashes started about four years before menopause, and let me tell you i had tried everything: herbal supplements, Wicking Pajamas, Pillow Inserts, and I even bought a new mattress. My poor husband was FREEZING and I was SWEATING while we fought about fans and the temperature of the thermostat. But other than Estrogen Treatments (Which can be dangerous… so I hear… ) nothing was beating my Hot Flashes until the ChiliPad™. Now both my husband and I can sleep comfortably.
