Nausea & Sleeping on Stomach!!!!!
If you're nauseated you could be dehydrated. First sign of it is nausea. Are you getting in all 64 ounces of water a day like most docs recommend? If not - up the water intake and you'll feel better. Try decaf tea as it will relax your stomach too. I slept on my stomach after a week or two but don't usually sleep that way. If you don't have stitches or drains you should be able to do it when it's comfortable for you to get in and out of that position without pulling any stomach muscles.
