Yep, you got it I have the stomach thing now too. Mine is abdominal craps which makes for great discomfort nursing or anytime. My hour on the couch trying to nap (when Jackson wasn't in smacking my head) wasn't bad. Sleep made the stomach aggrivation stop. So far nothing major has been unleashed, my stomach is just very angry.
It's going around town and it's going around in Norman too, so chances are it's going around where you live. Keep your hands washed and I wish you the best.
