I don't know how long this will last, but so far it's been about a week. One night I had been eating....more than I should have and I suddenly had somewhat of a sharp pain in my stomach. So, I got to my bathroom and the pain got worse. It last a few...perhaps 3 minutes? I haven't felt exact pain anymore since that time but ever since then, my stomach has been feeling sick. I feel nausea mainly when I lay down or sit down..but it's the most annoying when laying down. I haven't been feeling any better as the days have gone on. I'm a little worried cause I haven't really felt like this before. I have also been more gassy. In the beginning I had the feeling of vomiting but never did. I don't have those feelings anymore but I still do have a sick feeling in my stomach as if I was nervous. *Not sure if this is relevant but, the first two days I could not stop shivering at night...and it didn't help the pain. Now it isn't really pain just a sick feeling that doesn't get better when I eat, so i get full easily.
