What worked for me was just keeping a bowl of fruit on my desk. It sounds simple, but when I was too fried to think, I'd just grab an apple instead of reaching for chips. It didn't fix everything, but it broke the cycle.

Well, lily_sullivan82, those two hours might have been useful. Sum usually refers to added numbers, but total is the final count after all factors. For example, on a bill, the sum of prices isn't the total if you include a tip. Get it wrong and your math is off. It's dull stuff, but so is most careful work.
