Can you survive on pickles alone, for a while?

Almost every jar of pickles claims a serving of pickles has zero calories. Now clearly, this is incorrect and the result of exploiting some ridiculous FDA loophole, since anyone knows that cucumbers provide calories.

So let's say you're in a situation where you lose all access to food, but you've got effectively unlimited access to pickles -- like, you're trapped inside a recently abandoned pickle warehouse.

Could you conceivably eat enough pickles to survive for a month? Two months? Or would your body just shut down from all the sodium and acid?
