The cleansing process is based on the individual system. Every person works in a different manner. I can tell exactly how long the cleansing will be for you. The reason for this is every person has a different toxicity level as well as their diet, stress and exercise levels are different.What you should realize that if it has taken your body 15 years to get in the state where you are having troubling eliminating. Then in order to cleanse your entire system, the approximate time period before your system is totally cleansed is at least half of the time that it took your system to become compacted. In other words, you should expect to be cleansed in about 7 years. However, this is assuming that you have corrected your diet.
