At least I think it was. I was out to lunch with my wife and some friends and had just finished a nice bowl of soup with some brown bread, and suddenly I went quite hot and sweaty and felt nauseous. I excused myself and went to the loo where I thought I was going to vomit, but after about a minute, I felt ok again, and have been ok since. Was this a type of hypo? I don't know because it has never happened before.
