I have diarrhea now for going on 8 days. Stomach aches and sharp pains. I ve lost 10 lbs in under a week. I m nausea but not vomiting . Feel hungry but nothing tastes good . Only had fever the first 3 days. I get bad dry mouth even though I drink water and Gatorade. Nothing seems to help. I had the duodenal switch April 10, 2012. And this is the 1st time I ve been sick since.
