Spikes, I hope you feel better today. That would be scary to me, too. I agree that your gut assumption that you simply ate something spoiled/contaminated, by accident, is correct. It happens a lot more than many realize. What did you eat yesterday? You should throw away any leftovers and avoid buying that product from that store you bought it from for a while. Maybe report your suspicion about the likely product to the store or restaurant? It's possible they may receive additional ones. That's likely one way that recalls happen.
