Food Poisining?

A couple days ago I was very sick. It started after I ate at this restaurant with my friend. I had fish. About 30 minutes after I ate I started to feel sick and started to burp alot which isnt normal for me. My stomach was very bloated and I had major pain in my stomach. For about 5 hours I felt this way and then I started to get dizzy. I started throwing up 5 hours later after I started to feel sick, but mostly just dry heaving and that went on for the rest of the time

The next morning I felt very tired and low and energy and I had a low grade fever.

I felt better a couple days later

What do you think this was?

Thanks!
