i have my 2 morning cups, then usually a cup of decaf in the afternoon, just as a 'treat'.
My keurig just broke (they're shipping me a new one, btw - I was very impressed w/ their customer service), but in the meantime, I bought myself a Tassimo so I could have latte's, etc. I love it! Especially for the afternoon decaf (I put the frothy milk w/ it... yum!!) I do wish they had more flavors though.
