Grade: 2
Don't know exactly what I had. I had a really bad headache, and my stomach wasn't agreeing with anything that I ate. Managed to eat a bowl of cereal in the morning, and 2 pieces of toast at night. I wanted to eat more, but I knew it would be bad if I tried. I drank a bunch of water as well. I think it was a combination between dehydration and a stomach ache.
Got a bunch of sleep both during the day and at night. That really helped.
