Had 2 pieces of toast for breakfast and felt fine. Had a bagel and cream cheese with tomato soup for lunch, started to feel a little fatigued and gassy. Dinner was fairly low in gluten, just had a touch of bbq sauce that had soy sauce in it and then I decided to have a beer. As soon as it was finished, I developed a migraine and extreme fatigue. I was ready to pass out at 8 pm.
