I'm not an INFP, though I would think my thoughts would be welcome as no one else has posted here anyway... I've convinced myself I'm hypoglycemic; I definitely feel debilitated if I don't have something with at least a moderate amount of sugar in it at least once every 5 hours seemingly... I'm prone to psychosomatic dependencies it seems, so whether or not the hypoglycemic point is true I'm not totally sure, but I do rely on what is likely at least an above average amount of sugar just to generally function... I know this can often be a precursor to diabetes, which is a reason I've tried to be more conscious of my intake of such a substance too, at the moment I don't have any practical plans to drastically change my eating habits though (although I probably should to be honest...).
