influenza
"The only symptom I had not had from the flu was vomiting. I brought the Tamiflu home and took a pill. Within an hour I was feeling very nauseated I tried my best to ignore it and keep my stomach down, but within another hour I was in the bathroom vomiting horribly. Continued the entire night. Now the next morning I still cannot hold down anything. $100 down the drain, can't even take it"
