Lana,
You have now inspired me to try to go on a juicing cleansing. I am in full time employment so it may be more difficult to be strict but I will try!
Good luck with your efforts. I can see you that you will make it. I have lost 25kg about 10 years ago (I'm 33 now) and I have kept the weight off as I did i very slowly - over a period of 18 months. In the first 6 months I have lost around 10kg and I felt great. Then I have reached a plato and didn't lose any weight for some time. Finally, the rest of the weight fell off me as I was becoming much more confident, went out more, had a few relationships and started to excercise at least once a week. I am a very keen practitioner of "Callanetics" - it's a miracle how such low impact excercise can help to lose weight and truly change your body shape. Together with some "clean and healthy" eating, Callanetics has completed the job and I am now size 8-10 (European), which is about size 4-6 American (basically size XS and Small).
I've recently moved to Australia and had to buy a Callanetics DVD as we don't have any classes here. You can get it from Amazon second-hand and it doesn't cost very much. Also, a combination of Yoga, Tai Chi and Pilates (called the "Body Balance") is a great way to tone up.
Good luck again and thanks for inspiring me to cleanse my body!!!

Warmest regards,
