In August my old roommate and I ate at a wing place. He got sick following and it lasted over a month. Diarrhea, stomach cramps, lethargy, etc. He lost a lot of weigh too. His brother is a doc and sent him several different meds and eventually had to make a trip to see him and it took taking a stool sample to figure out what was wrong. It was a bacterial infection and he got prescribed antibiotics and it finally knocked it out. He was sick over a month and pretty damn miserable.
