I ate a hamburger with lettuce and tomato, no cheese, no onion. I felt not well about an hour after eating the burger. I started feeing stomach cramps and diarrhea coming on. I had diarrhea the rest of the night and woke up at 1am and threw up everything. I had diarrhea the next day and did not eat anything until 5pm the next day because of nausea and the fear of not being able to keep anything down. Symptoms did not stop until around 9pm the next day. Symptoms lasted over 24 hours.
