3 months sounds great for a first-time cleanse or cleanse for candida. :) It does take about 3 months' worth of total discipline to really lick it good enough that it doesn't come back and keep torturing you.

For maintanence, you can get a cheaper fiber-based cleanser, or switch to Oxypowder , which liquifies impacted fecal matter and would prevent a re-buildup, but really all you'll probably need is ground up flax seeds. Very cheap, all you need is a cheap coffee grinder. You can take the seeds whole, ground, or as a tea. It really helps the lungs too as a tea, ground up you get EFAs, whole you just give the fiber as they won't digest.

good luck on your cleanse, and be sure to let us know how it goes! :) We like to hear success stories, or tips, and reviews on commercial products.
