I don't think I have it but I think I may have had a bout with it this past weekend. Me and my friends went to eat at a Benihana-style restaurant called Fuji. I ordered tuna roll as an appetizer and steak and chicken, steak cooked rare. Afterward, we went bowling and stayed there for about 3 hours and bowled. We all then went to an ice cream place for dessert called Shakes that serves frozen custard and I ordered a root beer float. That's when things started to go downhill.....fast! After finishing the float, my stomach began to ache a bit but we all went to my friend's house to hang out. I began to feel worse and worse and more nauseated. I only stayed for about 30 minutes before heading home and feeling awful. When I finally get home, I couldn't make up my mind whether I need to put my face in the toilet or my butt. Tried the butt first and nothing came out and I stood up and I knew I was about to spew from my mouth. I started vomiting. After that I still felt pretty bad so I went and laid down for a minute but then started feeling bad again. Went to the bathroom to sit on the pot and then pure liquid came out, nothing solid...at all. Thought I was finished and I stood up had to sit back down and continue, thought I was done after that but stood up and had to sit down and continue, thought I was done after that but stood up and had to sit back down and continue, and so on. I was finally able to stop and hop in the shower and then go to bed. I still felt iffy but not too bad yesterday and today I am finally feeling like my good ole normal self. So, after those graphic details is it a possibility that this was food poisoning? I mean can it act that fast?
