The goal of any protocol is to get you back to a regular lifestyle with just maintenance care from then on. Most intervention should be just that - temporary intervention to get you back to balance.
Sensible health products are excellent. I also like Planetary Formula's liver cleanse, it's quite thorough, good grouping of herbs, not too expensive at all.
Improvement to bowel function can be immediate when you treat it comprehensively. :) It depends on how misshapen it is how long it will take to "cure," and really you must keep cleansing it in order to minimalize detox healing crisis symptoms anyway so... :)
Liver Flushes can be done as often as every 2 weeks so long as you're cleansing the colon thoroughly post-flush. Some people say you should wait a month to make sure the stones de-clump and move forward. I think it depends mostly on when you have free time! LOL! :)
