Me too!!! I usually walk as exercise because if I go to the gym and work out to hard or hear all the blaring music, it wires me! Or, if I am just at a party and talking to someone and the conversation is interesting I get so excited my head and body feel like i am in a warp zone or something and it takes a lot out of me...i usually leave partys very tired as a result. I play it off though so nobody knows, which is probably not healthy. Either way...I have that same reaction to excitement. Let me know if you find the answer to eliminating this : ).
