Hello, I am a 65 year old male with type 2 diabetes, and a 10+ year old cardiac stent. I was perfectly fine on this hot summer day, when I went to lunch at a Chinese restaurant, and near the end of my meal, a wave came over me where I didn't feel right in my body. My vision and hearing didn't seem at full function, and I felt a bit lightheaded and only the slightest sense of nausea. I also broke out in a cold sweat. After resting, and breathing and consuming a glass or two of ice water, it seemed to pass, but it was quite scary. I wondred if I might have had some kind of food allergy or food poisoning.
