9-5 is a survival of wits. Without backup for those long long days, I would be a puddle of visceral mess by the end of the day. Clif Bars make eating 6 times a day much easier. And my personal favorites are:

Peanut Toffee Buzz
and
Chocolate Chip Peanut Crunch

Of the holiday versions, I enjoyed the Pumpkin Spice one the best.
