Thanks for your repies

I have been trying so hard to stay sleeping on my left or right side, but i wake during the night with very painful hips lol, sometimes it's a no win situation I tell my husband to roll me over if he finds me on my back and he has been good by doing this. It's a hard habit to break when it's a position you are used to sleeping in.

I can't say i have felt dizzy or queezy by laying on my back though, but then again i am a bigger girl, so it might be a little harder for me to feel it, not sure. But it's something that has definately been bought to my attention by your replies
