<<Disclaimer: Verify this information before applying it to your situation.>> I know that a lot of celiacs have problems with other food intolerances and allegeries so I was wondering if anyone else had problems with sugar. If I eat a sugary food or drink a sugary drink I get stomachaches, headaches and feel groggy. Basically the only drink I can tolerate now is water. I am going to be going to the doctor's soon but I was just wondering if others had a similar problem. Thanks, Kim
