This past week I went to Costco and bought myself a Keurig single cup coffee machine. I just opened it a little while ago and -am already "sampling"The coffee is really good. Caffiene has never been a problem for me but, I am definitely a coffee addict and with all these little cups just a few brews away -well sleep is over rated anyway!!!! Now if I could only find a wine machine like this- I think I would be in heaven!!!!Love and energy, Vicki
