I know how you feel. My pregnancy last year had me feeling like that. I did find that not laying flat helped a lot. I had a large flattish, tapered foam wedge cut and found that if I lay on that, it helped to control the "rolling bed" syndrome.

I also found that keeping the fluids up with things like fruit juice and milkshakes helped to control the blood sugar levels and eased the night sickness off a bit so that I could at least sleep.
