I was gluten-free most of last year and felt much less lethargic. If I eat a bagel or pancakes for breakfast, I’m exhausted for the rest of the day. I was really good about staying gluten-free then I had the gluten-filled gateway drug: A New York City bagel. I’m going to experiment with being gluten-free again this month and I’ll be concious about comparing how I feel now to how I’ve felt when I’ve eaten lots of gluten. I also started reading Wheat Belly and am interested to learn the medical reasons for being gluten-free.
