To combat sleepiness and nausea, I planned to splurge on an 'expensive coffee' with the highest number of espresso shots 'as allowed by law' (is there a legal limit somewhere?).
In my research for the 'legal limit', I came across this cool site that calculates how many shots of espresso it would take to kill you...depending on your sex and weight.
I found that it would take 168 shots of espresso to kill me.
"...Yeah!!!!! Bring on the caffeine, baby....."
