I want to make a completely nonfat coffee drink that tastes good?

Any recipes you can think of? And I want to drink this drink often because I love coffee, and it helps me get through my day, but my stomach gets upset if I drink it plain. I've tried putting in cream and sugar, sometimes i blend it with ice and milk, but it still doesn't go down right. Its only when I have a mocha drink from a coffee house that I enjoy it, and am awake for my day. Any healthy, coffee mixtures that you can think of that would be okay for me to drink every morning?
