Does anyone else get nausea and light-headedness?

I keep coming back to post my long list of symptoms. It seems I have just about every one in the book.
Lately I have been feeling very nauseous and lightheaded throughout the day. I know I am not pregnant, but feel just like I did when I had morning sickness. Sometimes it also feels like motion sickness. I am going tomorrow to see my gp. I think my doctors just think I'm crazy, but my symptoms are very real. Oh how hard it is to find a good doctor. Anyway, is this typical of peri-menopause? I am pretty certain this is what I am dealing with, but want to get checked out to be sure nothing else is going on.
