Night sweats?

I know this is TMI, but Ever since I can remember I have woken up in the middle of the night completely soaked. The seats around me would look like someone poured water on them and I would have to change my pjs. This doesn’t happen every night, but it seems to happen mostly when I am in a deep sleep. Apparently, this also happens to my mom And brother. 

I never thought anything about this until my husband saw an ad in the newspaper for a dr who specializes in night sweats. When I googled it (for a woman with anxiety, I know Google is risky lol) it was all related to menopause. I don’t think that is what it is, considering how young I was when it all started. 

Do any of you get night sweats? And what do you do to help?
