It doesn't sound like you're going into a deep restful sleep. Have you discussed this issue with your doctor? I had an issue where I would sweat from my waist to my knees every time I went to sleep. I was sopping wet! It was to the point that I was having to sleep on a towel. It turns out that it was a symptom of an infection. I mentioned it in passing, it seemed so small. I would recommend talking to your doctor.
