Feeling yucky

I have been awake since 1:30am, been up since 2:00.  With all the symptoms I am feeling, I decided to take the time to research and I think my bread eating days are over.  I know I need to figure out if this a yeast, or gluten, or wheat allergy.  But frankly, I am feeling so lousy that I don't even want to test them out.  When i figure how to isolate the ingredients and am feeling better, I know I will test them.  But the thought of poisoning myself on purpose just holds no attraction to me at the moment.  I feel that bad.
