To answer the question about the pre-packaged cleanses sold in health food stores, yes they do work. They have a bunch of herbs in them that help with the specific cleanse that you are trying to do. Otherwise, you can try other fasts, like the Master Cleanse. It is really intense, but you do get results. I'm sure you have heard of it, the one where you only consume a mixture of lemon juice, cayenne pepper, and maple syrup(and water, of course)for up to a month(we have only lasted 7 days on it!, but know people who have done it for a couple of weeks or more. You can also check out Linda Page's Healing book, it has a great area that has cleanse ideas for specific areas of your body(liver, skin, gallbladder, lung, etc, etc.). Her cleanses are a little bit more managable. Make sure to take the herbs milk thistle(silymarin)and dandelion. They help cleanse and support the liver. If you have never done a cleanse before, just realize that you may feel a little yucky, it's part of the process. You will be stirring up those toxins and eliminating them. Make sure that you are going #2 at least 3 times a day during your cleanse. If you aren't , take a laxative tea like Traditional Medicinals Smooth move(or try senna leaves, but not too much, they are very potent). And remember that it is totally worth it! It may be rough at times, but you will be glad you did it in the end. Good luck! (PS My wife and I do work in "one of those health food stores".......the products that are sold in natural food stores are very effective, no snake oil here!
