Medical axioms have a bad history with pwME; they not only may not apply, they can make us worse. You might as well start with asking about our mood when we are crashing, or before we crash, or after. Not only is mood irrelevant as a causative agent, those who query it have mischaracterized us and our disease for decades. We have been victimized by dogma. Moreover, not sure even patients will answer the questions correctly. If correlations are involved, we just might not have enough of the requisite insight. This is not a slight against patients. What if diet matters, and you don't know that? As for sleep, it's so hard to come by, I long ago stopped looking at it as restorative; i look at it more today as a hard-to-get-to port in the storm, a shaky staccato respite from feeling terrible. I think it's downstream, but I don't care anymore. I'd be real careful about asking the right questions, and not embedding what might prove to be dangerous assumptions. That aside, this seems to be a good idea. You have to start at the beginning, and we seem to have missed that step for the last four decades. Common sense is good, and for me, a refreshing change of pace.
