We had a recent thread discussing coffee and how most people thought that regular ingestion was Ok. We drink lots of coffee, Coke and other caffeine enhanced beverages regularly in our daily lives without thinking twice and in most cases it's thought not to be a problem but for some people it's not that simple.
Caffeine is a stimulant and as such has an attraction for athletes wanting to take every advantage in there endeavour to be successful. Dosing up on caffeine in some sports has become commonplace, just part of the game but in an article published in a Sunday news paper, the repercussions are shown to be significant for some people. http://www.sundaytelegraph.news.com....-28778,00.html
It leads me to believe that it can't be good for anyone who regularly requires her/his body to perform to it's perceived best and beyond.
