<<Disclaimer: Verify this information before applying it to your situation.>> In reply to Lauren and Amy: I have also been diagnosed with Chronic Fatigue syndrome, which has gotten much better in the last few years. In fact, my usual reaction when I have eaten something I shouldn't have is mild diarrhea, severe headache, sleeping for days on end, and nausea. My symptoms are a lot like the chronic fatigue in other words, which has made me wonder sometimes if the chronic fatigue isn't really the CD . . . Wendy
