Having been off wheat & dairy for about a week (and losing weight) I have today eaten some wheat based product . However now I feel hot but cold IYKWIM and have a tummy ache also feel a little woozy. A couple of years ago I tried Atkins for a few days then simply had to have a slice of bread I was so hungry. That night I also felt hot to touch but cold and real bad tummy with not nice consequences. Does this sound like an intolerance?
