Planning for the apocalypse

In the event of the apocalypse, if you were trapped in your office, how long could you survive off the provisions contained within?

In my office:

5 Clif Bars

4 noodle bowl lunches from the farmers market (kinda crunch unless I can find hot water)

1 box whole foods cereal and fruit bars

4 packs instant miso soup (also rather unappealing without water)

lots of tea

In my desk

1 tin altoids

1 package Meatloaf with brown onion gravy from a MRE. WTF? I think this is left over from last years Burning man supplies.

1 package turkey tettrazinni, also from a MRE
countless packets of hotsauce, honey, mayonaise, mustard, bbq sauce, sugar, splenda, salt and pepper, mostly looted from the nearby Chik-fil-A

4 doses DayQuil, in case the apocalypse includes nuclear winter and I catch a cold.

8 does Prilosec, in case my meager provisions give me heartburn

(no subject)

That makes 3 cancelled photoshoots in the past week :(
