Hot flash support! I've tried everything! Community Group

Help! I'm 48, in pretty decent health. A little overweight but not too hefty. I have been experiencing major hot flashes for about a year. I've tried the hormone patch which worked but made me spot for an entire month and a half! And now I'm trying black cohosh root supplements but I'm still waking up with night sweats and having pretty regular hot flashes all the time.
