Mixed Juice Fast

[Rawzula]

I want to do a week-long carrot/apple/ginger/celery juice fast. I would like to know: how much of each ingredient should I get?

I already have one 5lb bag of carrots, and 2 Granny Smith apples.

To get about 12oz I use 4 carrots, 4 celery and 2 cloves of garlic. I would guess with an apple you can halve the amount of carrots/celery.
