you really need to see a gp about this problem, no one else can help you. Urine(in case you didnt know) is made up of urea- toxins that need to be flushed out of the body immediately because they are toxic!!- so why would you want to drink it after your body spent a couple of hours flushing it all out of the system??
My advice, take a break from it and try green tea (or even a nice fruit smoothie) ... a lot lot healthier in many ways and once you have tasted it you'll never want to go back to drinking what you are now
