<<Disclaimer: Verify this information before applying it to your situation.>> Ironically, after all the back-and-forth on the listserve about the studpidity of unneccessary gluten challenges, I just did one by mistake. I bought vitamins, carefully checked the fillers, and completely missed the barley protein in the active ingredients! Well, I found it a few hours after the first pill. I'd actually been having digestive troubles and wondering if it was gluten contamination - no. Now I remember. The abdominal pain of gluten is nasty, but my real problem is the inability to remain still and awake at the same time. So, a quick question in this rambling post. My Monday midday class is dull and long, and I often have trouble staying awake in it - and the trouble is worse as class goes on. Other students are eating lunch throughout class, and I'm sure several courses of gluten-laced breakfasts were eaten in the room before that. It feels like gluten rather than boredom. Any ideas of how to protect myself from this kind of environmental gluten? Thanks. Elizabeth
