Me my my kid have the same symptoms. We spend a lot of time at the local MX tracks and suck a ton of dust. Its been like 4 weeks and we are almost back to normal. We pretty much had VF symtoms as they read off the list. I can do STF Wed at 6pm. Its good to know you carry some juice..if anybody ever has a dead battery! I have a buddy that has a programable giz hooked to his heart that is monitored via a wireless hook up at his home. His doc can program the thing for "better performance" with a laptop. He's still desert riding! Glad you're OK!
