<<Disclaimer: Verify this information before applying it to your situation.>> I know someone who was having problems absorbing medication which was specifically for nerves. However, she has just gone for another biopsy on account of still trotting to the toilet after every meal. I don't know the verdict, but I would definately check your diet first. My gastroenterologist seems to think we absorb sufficiently enough once we're on a gluten-free diet. Gail Cole, Perth Australia c/o ([log in to unmask]) This is fun!
