Well, I don't know how, but I escaped without vomiting. Turns out my mother infected nearly the entire family on Thanksgiving. She had it the day before but thought she was ok, but was really still contagious. Out of 17 people, 14 got it. The hubby started throwing up shortly after the kids, and I really thought about going to the ER to be safe. I did have a couple of phenergan suppositories, that were two years old, so I used them, but was already in the throes of it. I had horrible diarrhea and stomach cramps and general lethargy, but never felt like I was going to vomit. Don't know if it was sheer grace of God, or if it was because I had just had the surgery and my stomach was so messed up that the bug couldn't take hold, or (although they say penicillin doesn't work on viruses) if it was the massive shots of antibiotics I got on surgery day. Either way, I hope NONE of you get it, it was particularly virulent AND violent.
