I can tell you're from the north...Pop...haven't heard anyone use that one in a while. I'm from Illinois living in Texas and everything here is coke...where I come from we call it pop...but I digress
I drink regular coffee and diet coke whenever I want. I'm still losing nicely, but I think that if I cut them out I'd lose quicker. But sanity is key here so I do what I do and still keep going. One day I want to try to eliminate them both all together, but until I get a job where I can show up at 9am I'm drinking my cup'o'joe!
