 What a great medical explanation Kyle!  My reaction to xylocaine has never
been medically assessed, but I can tell you that I drink coffee and soda like
there is no tomorrow (oh my, I hope that wasn't a prophetic comment).  I have
already had five cups of java this morning.  I don't seem to have ill effects
from that in terms of heart rate, but if I don't have coffee every few hours
I get a terrible headache.  I guess this means I am physically addicted.
