Sounds like you had a strong case of food poisoning. Most of these are self-limited and don t require any kind of antibiotic therapy. Treatment is symptomatic. Push the fluids, starting just with clear liquids. If this is tolerated, add simple easy to digest foods such as dry toast, crackers, hot cereals. Avoid milk and fatty foods initially. Potassium-containing foods such as bananas are helpful, since you probably lost a lot of potassium with the diarrhea and vomiting. Sports drinks such as Powerade or Gatorade may be helpful to supply some of these lost nutrients. You should feel better in a few days. A lot of your weakness etc may be due to dehydration, so drink lots of fluids. Hope this helps.
