Cutting out dairy? Like yoghurt, milk, cheese, ice cream!??! GOOD LORD are you crazy! *grin* (Sorry, dairy nut, perhaps as much as I love chocolate... Mmmm... chocolate... Mmmm... Oh, where was I--)

My doc ruled out allergy because I have it primarily on one foot and not the other, hence it wouldn't be a factor of laundry detergent, carpet, and I didn't wear any toe rings (she did ask!).

Stress is probably a big factor-- I'm about to take my quals, which in graduate school, is a "do or die" scenario where my entire life may crumble before my eyes, no exaggeration.
