Sleeping on my left makes me feel sick?

overtonhayes

This has been going on for a long time now. It actually happened even before we found out I was pregnant, but calculating back I don't think it was a problem before I got pregnant. Sleeping on my left side makes me feel really, really sick. It doesn't make a difference whether I've just eaten or I go to bed hungry, or any variation inbetween. I can't lay on my right side for more than a minute before I have to turn over because I just can't do it anymore,

Does anyone know what causes this? And how important actually is it to sleep on your left?
