until I was diagnosed with a rare extreme form of it (they tell me in a year I may be cured) it socks all the energy right out of ya. Im exhausted from a 6 hour trip to illinois just from riding. I wasnt even driving. just sucks everything out of ya and the CURE well its the worst stuff I ever tasted. YUCKIES. Peeps eat your liver and onions..dont get short on iron reserves as badly as I had it become. mine they think was internal bleeding for a prolonged period of time but they really dont have anything thats proven yet...Take care of yourselves KIDS ~
