Cgallagh bought a coffee and espresso maker for my big Five-Oh. We've developed a liking for a double shot of espresso + foamed 1% milk + coffee in a 16 oz. mug.

I'm good for the entire day.
If I indulge in a cold coffee drink I usually have it before 4 pm so I can sleep at night.
I rarely drink sodas; the carbonation bloats me.
Four times in my life have I stopped drinking coffee for longer than a month: During both pregnancies, once when I was 22 on a bet (I won $200), and in my 30's just to see if I could. Took some getting used to but it wasn't the end of the world. Life is good; coffee makes it better.
