Suggest Remedy For Severe Night Sweating

I've been having frequent night sweats and am wondering if I should see a doctor regarding them. They occur ~3 nights per weak and wake me up from my sleep. They are often associated with bad dreams. My entire body is drenched when I wake up and often have to go "towel off" before getting back in bed. I have to sleep on top of the sheets when I return as the bottom sheet feels damp.
