I discovered this therapy after searching a natural cure for my husband's health problems. You can read my testimonial at http://curezone.com/forums/fm.asp?i=124703 .
At first I was like you really discusted about the idea of drinking 'my urine' and even applying it to my body (although we eat eggs without having second thoughts about where it comes from...). After reading several articles, books and seing the results on my husband I cautiously started experimenting with it. I had to try it. It solved my sleeping problems, joint pains etc... I still have taboos left deep inside, but it helps me too much to stop. I stopped for approx 1 month and was starting having problems sleeping again. My health is more important to me than taboos or predujists. My husband doesn't have any problem at all with the idea of ingesting his own urine which is in fact derived from his blood (life force). When it comes out of the body it is perfectly sterile etc... the small doses of toxins acts in an homeopathic way to detoxify, cure etc... you should read some articles on the subject and maybe try it ??? ... unless you are in perfect health!
It took approx. 5-6 months before I really started sleeping better (7oz morning and at night). But in the meantime, I realised that a few drops of urine under the tongue would relax me and most of the time help me get back to sleep. Sometimes I would wake up 2 - 3 times per night to put a few drops under the tongue.
As for my joint pains, I imagine it took about the same time. I just realized all of a sudden I could get up from my chair after a movie without thinking about it. I used to go very slowly and was trying to hide the pain in the joints. I was 52 and felt like 85. I also know I have more energy. Three years ago it would be hard for me to get up when I would kneel down to help a student. I realized last spring that I could get up much faster without thinking about it. As for the stubborn pain in the hip I was really surprised it went away after applying urine compress for one night only.
I was approx 15 pounds overweight. I lost 10 pounds in a month and a half (august 2006) after following some of Kevin Trudeau's (Natural Cures They Don't Want You to Know About) advice on how to lose weight and maintain it there. I think the Apple Cider Vinegar (unpasteurised and organic) had a lot to do with it. Also the walks in the park (oxygen) must have helped (eventhough I was going to the gym before). If you want the chapter on 'loosing weight' I could send it to you. It is already scanned. Just send me your email.
Good luck and hang in there. You are still young...
