Half and half does not have sweeter added - a coffee adder like Mocha Mix or the CoffeeMate additions would.

I'm very flexible with what I add and I've found few detrimental aspects. I like to make vodka penne and I've made it with everything from 1% milk (which I drink at home) but that was a little thin... what worked especially well was Lite Sour Cream (which we use for all things sour cream) - the added tang was a benefit and the thickness of the sour cream actually made it very creamy without a lot of added calories and fat.
