bad almond milk or gluten overdose?

Last Sunday night I was up all night throwing up. I had eaten at a new restaurant that night and decided to consume a large amount of gluten. I also had some almond milk that evening. Don't know what caused such an upheaval. It took my body a few days to recover I think. It wasn't food poisoning because no one else eating at the restaurant with me got sick and I shared a dish. Anyone ever had bad almond milk? I normally avoid gluten, but the excitement of a new restaurant got the best of me I suppose.

Or it could have been a virus.
