I have also had a change in symptoms, including the kinds of food I can tolerate. For example, I used to eat oatmeal regularly. But two months ago, it gave me severe heart palpitations. Recently, I have been able to eat it again.

A wide range of symptoms seems to be a hallmark of this illness for me. The symptoms fluctuate wildly, both in terms of intensity and frequency.

Like others, I am learning not to push myself. On more than one occasion I have started to feel better for a few days so I would increase my activity level, only to have a setback. The good news is that I am very gradually beginning to feel better. (It just gets discouraging when I have a setback. But the setbacks are getting less frequent.)

Has anyone else found that a good night's sleep seems to make a difference? If I get a solid 7-8 hours of sleep, my symptoms often feel less intense that day.
