Yes thanks. That makes sense. I started to eat some simple food now and I am beginning to feel better.
Minor food poisoning that has already went away partly does not need any treatment. If you do not feel like to eat, you don't need to...if this won't cause any additional problems.
Nausea may be partly due to dehydration if you haven't replaced lost fluid. Plain water or orange juice, bananas, bread, toast, cookies...should not cause any additional nausea, I guess. Avoid meet, eggs and other heavy protein/fat food that stay in the stomach for several hours.
