On Monday I took with diarrhea emptying my bowels to the point where just boil was coming out and then went to sleep for about 25 - 30 hours every now and then getting up to get a drink or use the restroom. I felt stomach sick, stomach turning, but didn t throw up. Thursday was the first cooked meal I had eaten since Monday and before that was just a half banana and a few crackers the night before. I still have fatigue, no energy. The question I have is should I just let this wear off or go to see a doctor? Is there anything I can take, if I have a virus of some kind, to get rid of it.
