Just wanted to follow up on my own thread in case anyone else is struggling with night sweats/hot flashes primarily at night during menopause. For me, and of course YMMV, Reminfemin (black cohosh) has totally done the trick. From the time I'd been on it for one week, I have had no more than handful of hot flashes overall. I was having many per night before, but now it's been a couple of weeks since the last one. 
I am completely surprised as I was hoping for an improvement but got a complete cure! No side effects that I've noticed either.
