Night sweats

Does anyone know of a natural remedy for night sweats. I wake up drenched in sweat 2 weeks every night before my period starts. It effects my sleeping, mood, etc. dr says getting back on birth control would help with it all. I'm 32, I've been on birth control since I was 15, stopped taking it for the last 5-6 years.. There has to be something else to take besides prescription pills
