Welcome to HealingWell!
It sounds like you may have Celiac's.... Have you been tested? It isn't that uncommon to have this intolerance. In fact, there was just another member on here asking about
it. Hopefully s/he will be around shortly. You know, you could probably do a "Celiac Diet" search on the internet and find a whole bunch of foods and recipes to help steer you away from wheat. It might be hard at first to stick to wheat free, but it will probably get easier as time passes. Not to mention you'll be feeling so much better that you probably won't want to go back.
Good luck! I hope someone else comes along shortly...
