Gotta tell you all. I've been on it for a month and a half. I have no bad reactions to msg. Never have. But I was having about 20 flashes a day, and sweating all night long. I am flash free for the first time in 4 years. I tried all the herbals, the effexor, accupuncture. NOTHING has worked to stop them. I'm going out to buy winter pajamas this week. There are no hormones in this stuff. Both my gynecologist and my breast surgeon at Yale have no bad things to say about it, as it is non-hormonal. The quality of my life has improved a thousand fold since I started it.
