A good part of the conference was focused on fibromyalgia and CFS.
Have you heard about sleep disorders and fibromyalgia? Apparently most patients have an alpha wave sleep disorder that prevents people from hitting the stage of sleep (stage 4) where neurotransmitters are generated. So sleep is not only non-restful, but it's non-restorative. Causes big, big problems.

Anyway, I'm taking the flax seed for the cancer thing. It's been shown decrease cancer risk in women. (But in men there is actually a correlation with increase risk in prostate cancer)

Guess you gotta weigh the risks vs. potential symptom reduction.
