Two weeks ago i was sick for five days. Diarrhea only in the morning, had no energy, no appetite. Yesterday started with diarrhea, then a lot of belching, bloated. Five hours later still diarrhea but worse, then i vomited about a gallon on undigested food from a meal i had ate in the past 24 hours. I continued to have nausea, diarrhea then 3 hours later was on toilet felt if i was going to pass out then i vomited again about a pint undigested food. I gradually started feeling better but 24 hours till i felt like eating. Two weeks ago and yesterday episodes followed eating out and fatty foods several days in a row with last meal eating pork.
