I would also recommend having your adrenals tested (saliva test). All the symptoms you mentioned can be attributed to adrenal fatigue. Dr. O talks about it somewhere on this site. The long-term stress of exposing your body to gluten and other allergens can fatigue or exhaust your adrenals, and they are one of the last organs to heal after eliminating the offending agents. Adrenal fatigue can be treated with supplements (mild cases) or hydrocortisone tablets.
