Can You Overdose From Caffeine?

Yes.  As a 17 year old girl from England can attest to, as she drank seven double measures of espresso and began to hyperventilate and have heart palpitations.  Certainly it seems that limiting ones intake of caffeine is a wise idea.  Despite the fact that my own family owns a small coffee shop chain, I've probably only had a half dozen cups in my life.  I still intake caffeine but only in small doses when it's in chocolate or the occasional soda or tea.  I've thought of stopping all together but I feel that the effects on my body with respect to the small doses of caffeine are not quite the same as small doses of alcohol or drugs.  I'd like to know where other people stand on the issue of caffeine and Straight Edge, so drop a comment with your opinion.
