Sometimes. It doesn't keep me awake if I do, I just don't want to drink the nasty slop here at work but can't justify leaving so late in the day for a coffee run.
I used to but now that I've given up diet coke for the most part, I'm much more sensitive to caffeine so it keeps me up if I drink it after noon. Hi, I'm old.
