How many hours in a day?

My days continue to have too few hours in them.  I keep wondering when I will either (a) take on fewer things to do OR (b) figure out how to subsist on fewer hours of sleep.  I have determined my limit on caffeine intake already so unfortunately increasing coffee intake is no longer an option.  I usually reach my limit at about 10am, which means I have a whole lot of hours to make it through on fumes.  I have to admit that hiding the acidic effects of 3 shots of espresso in 12 oz of milk really seems to help, but at $3.55 a drink, the new limiting factor is money.  And as a student I don't have much of that either.  I guess that pretty much sums it up pretty well.  As a medical student, triathlete, Survivor contestant, personal trainer, girlfriend, owner of 4 rescued animals (ie: zookeeper pretty much), and perpetual neat-freak (I struggle constantly to clean up after for large fury animals, I am short on time and money.  Can't wait until I have a job with some free time and some extra cash. Isn't that how it's supposed to work?
