I know that if I get up in the morning and realize I have totally depleated my espresso bean stock, I will not be in a good mood the rest of the morning.
I can go without food, water, sex, cigars and liquor for quite awhile. I do not know if I could last more then a couple of days without my morning espressos.
Get the espresso machine.
I have my continental European friends to thank for this addiciton. I never enjoyed coffee untill I had the "real" kind in Italy and Germany. Nothing cures that Oktoberfest binge like a good espresso in the morning. Especially when you do it for about 4 nights in a row.
