I would recommend avoiding dairy too.  People with celiac disease are often lactose intolerant and it's possible that it may be irritating you and keeping your stomach upset.  I really hope you're not vegetarian because meat is about to become your new best friend.  A nice propane grill combined with fresh meat will do you a world of good.  Processed crap will just about kill you. I hope you start feeling better soon.  I'm having trouble eating right now due to stress and the resulting nausea. I've been losing about 5 pounds a week, so I know how you feel.  Right now, I've altered my diet to graze throughout the day, just a few bites at a time so that I can get some nutrition without causing more issues.  So far it seems to be working.  Maybe that trick will work for you too.
