Lettuce and shrimpscampi. About half hour after I ate the house salad I kept feeling sick but would take tums. We ate at 12:15 all throughout the afternoon and evening I felt sick. At 9:15 vomiting up shrimp and something black. Which could have been the lettuce. Kept getting worse and came more violent and often. 8-10 times an hour until 6:30. I had no desire to see food or drink about 7am I was thirsty and drank sips of water. Still very weak but glad pain is gone, I thought I was going to die.
