Welcome Jen! The Gluten File (click on it near the top of the forum) has a wealth of information about gluten sensitivity and testing. My family is self-diagnosed too. It started when my 5yo began having chronic tummy aches. The doctors put him through a battery of tests and deemed him "fine" ... while the chronic tummy aches continued. We removed gluten from his (and our) diet and the tummy aches went away. The added benefit was that the rest of the family felt better too. I'm a firm believer in foods affecting our health! Oh yes, and I take 2000mcg of methylcobalamin daily! Good luck!
