Cheeseburgers. Or chocolate. Or raw tomatoes. Actually I have a slight allergic reaction to eating tomatoes, but I can't do without them so I eat them anyway. Probably not good ...
Normally I would say soda. That's my addiction. But I just started reading Kathleen DesMaisons books on sugar addiction because I am diabetic so I might actually have to choose between soda and living.
Cheese. Cheese makes everything better. I have yet to find a food that can't be improved by adding cheese. Not saying it doesn't exist--just that I haven't found it.
Bacon, seafood and butter. For awhile they thought I might be allergic to scallops but that turned out to be an allergy to some weird Greek seasoning thank God!
Pizza. I've been seeing a nutritionist and have effortlessly been able to switch over to whole wheat crust and mostly vegetable toppings. My challenge now is to not eat a whole pizza in one night, or, well, yeah, just not order it.
