The only thing I can see is the KIND bar?... Have you been eating that for a long while or? Also you said you had been feeling nauseous yesterday all day, so was that before or after you ate? What did you have the day before yesterday?
LOL, I was gonna suggest that you may be pregnant when I first saw your thread title without clicking on it first.

Today has been much better for me....still feeling that strange nausea feeling slightly but it's definitely not as bad as it was the past two days. I'm thinking it MIGHT be acid reflux but i'm going to wait it out and see how I feel in a few days.
