On Saturday Feb. 22nd at about 2:30, I had the steamed mussels in a tomatosauce. There were a lot of them, and they tasted fine. But several hours later, I vomited twice. Very upsetting, as we were still in the Strip District, and this was in the parking lot of another restaurant (I hadn't eaten anything else), as I had no control over it. I had diarrhea off and on all night. I've eaten mussels many times before and have never had a reaction like this.
