Possible food allergy

Patient: I ate dinner then went to take a nap. It was a three hour nap, but when i woke up. I almost felt like I was drugged and have been really itching ever since. As well as being super thirsty. The only new thing I have eaten today is the gorgonzola cheese. It came in a stouffers skillet dinner. I’ve never had these symptoms before. I was wondering if this could possibly be a food allergy.

Doctor:
