I love my one or two a day...like others, I can have a cup in the evening and drop off to sleep! The bourbon helps too...
I find it rather ironic though, that the guy that invented those little cups for the Keurig coffee makers wont use them.
He said in an interview that not only are they "non environmentally friendly" but that using them raised the cost of a pound of coffee to about $40.00/lb.
