Well you did just GREAT! Resisting Chinese food had to be a tremendous effort on your part--nothing smells better, huh? Just TOAST drives me nuts! I don't have the urge to eat it, but smelling it is literally like tasting it. So weird.
I live on southern Baja, and we used to have to drive 2 hours for basics like toilet paper. I would get up once a month or so and stock up--it's insulting to overpay for TP! We still have to do The Drive if we wanna buy exotic things like underwear!
That back pain can definitely be stressed kidneys. Drink LOTS of extra water and flush those puppies out!
