Of note is the bit about uncontrollable rage mentioned in the alternate-health and Wikipedia entries, and the example of Apples in the alt-health writeup. This is of particular value given the fact I've been supplementing my diet with apple juice of late- unlike ALL OTHER JUICE EVER it doesn't give me heartburn. Days I consume apple juice happen to coincide with days that I get pissed easily and enjoy taking it out on anything that moves- many of these cases being triggered by the personal habits of coworkers psycho-distorted to apocalyptic levels of premeditated intent. The sorts of activities which are under normal circumstances merely quirks or annoyances.

Same thing appllies at home. Kicked the everloving shit out of a chair in the living room, seemingly deliberately left in the doorway to the kitchen by my roommate. I say deliberately as it's been there Every Single Fucking Night for the past six months- sometimes trip-positioned, sometimes not. I kicked it so fucking hard he heard it upstairs and inquired from a safe distance- I bellowed something to the effect of being sick to fucking death of tripping over The God Damned Chair and, realizing I sounded Just Like My Father, stomped up the stairs to google up things like ("apple juice" rage hypoglycemia) and (rage hypoglycemia) and similar, as my brainmeats have a distinctly apple flavor to them, despite having laid off the stuff some six hours previous.

Diagnose-Me has a relevant list of symptoms, specifically the Symptoms - Mind subcategories, which apply in their entirety.

Obviously, I need to get this verified by somebody that pays three times my salary in malpractice insurance, since they're the sort of person who gets paid to tell people - authoritatively - what they really don't want to hear.

Obviously, Apple Juice and juice of any kind gets retired for the interim.
