Oh god, I had food poisoning last month and I couldn't even drink a cup of water without hurling. It was nasty. All I could do was sleep for 2 days. It actually took a full week before I was completely back to normal and about 3 days before I moved to solid food. It sucks ass getting sick, but this is worse because it's not like you have a cold and are coughing. With this, you can't even really eat or train.
