I hope this reply reaches you, i am curious how things turned out? i would think you had leaky gut and if you kert taking the glutamine it would help heal it. your story caught my attention because i have the same problems and symptoms and more. i to found licorice helps and was taking the regular but have ordered the DGL. i am taking the glutamine as well. i too tried most of the supplements and more that you tried. i was happy to find someone with the same problem as i thought i was the only one, i have never found anyone else who was experiencing the same things. please reply with an update to your condition if you can, thank you.
