I've talked to a few Se/Ni valuers about food, and it seems that for them hunger is much more of an impulse and for Ne/Si valuers it's much more of a general sensation. It's as if the world is a series of impulses and stimuli that have to be satiated, or so I've come to understand. Is this the kind of thing you're talking about when you talk about your impulsiveness?
I'd guess beta irrational. SLE? Maybe?
