What is cowboy style? Did you pour smashed beans into a tin cup and boil it over a mesquite fire next to your bed?

I like a large cup every morning, drink half quickly and then sip it occasionally for an hour or so.
I have been using sugar but want to switch to something else to save calories but I need some sweetness.
Yes, drink some coffee, drop a deuce and hit the road to work.
When I get home I usually have half cup with half milk iced for a little 3 pm snack/pick me up.
