When I used to drink coffee regularly, I kept a small jar of powdered whole milk on my desk at work, and added a spoonful. Now I only occasionally drink decaf at home.
I like *MY* coffee black, but the coffee in the breakroom at work is quite nasty, and I had to add the milk to help choke it down (i.e. feed my caffeine addiction - I sure wasn't drinking it because it tasted good).
I quit drinking caffeinated coffee over a year ago, and now I never NEED to drink coffee! I make a cup of decaf at home if/when I want it. Sometimes I do make it strong and put it 50/50 with frothed milk, though. Mmm.
Never sweet though, sweet coffee makes me want to gag!
