More than a feeling

Me and the doc have yet to arrive at a final conclusion but we are pretty sure my ticker isn't dicky, final tests next week but as I am even more active than usual, 3 hours training today/tonight(hence upgrade to work facilities, my very own parking space) and have not carked it, it would indicate that weird sensations in chest area are related to something else. He thinks my self diagnosis of caffeine allergy is interesting, and as I have switched to caffeine free beverages and almost no chocolate and have not felt so ill it looks like I am the winner of the diagnose whats wrong with me competition.
