Yes, many people. It takes a few months to do a good job, but more importantly, before ANY DETOXING, you must prepare your body for the process or you can do more damage than good. All these people promoting detoxing from this or that product fail to warn people of what can happen if your organs are not prepared properly before doing the detoxing. Your cells must be up regulated with energy or the detoxing will cause the heavy metals and toxins to be driven deep into your tissues, instead of leaving your body.
Take a test of your first morning URINE pH when you wake up. If it is between a pH of 6.4 to 7.0, you have good cellular energy and can do the detoxing. If it is lower than 6.4 pH, don't do it.
Any infection in the body depletes it of minerals and your cells will suffer the low energy issue. You need to contact a Certified Nutritional Therapist that understands QRA testing, etc. to really help you in getting this job done. It is important that it is done correctly for the best results and long lasting health. Many people believe that detoxing is a waste of time, but that is simple ignorance of how the body works. Of course you need to detox, especially if you are eating the SAD (standard American diet). Just make sure it is done correctly.
good luck to you
