i figure if i eat well, and smart, 80% of the time, pigging out one day every now and then won't be detrimental to me. but that's me. and i find i can no longer pig out, except for 2 days a month, but any way, that 20% of the time that i give in and eat at the cafe, or sonic, or mcd's, won't hurt as long as 80% i'm eating good, healthy foods, and not too much of them.
