I've found that most flavored syrups and even flavored coffees just don't taste very good to me without creamer. Unless I use a ton of vanilla syrup, but I hate taking in that much fake sweetener each day.
It may sound crazy (it does to most people) but you could use skim milk in your coffee. I'd recommend working down to it.. either by mixing it with your creamer of choice, or moving to whole milk then 2% then skim. It has less calories, less fat, and I think more protein. So at least you're getting something useful out of it.
If your creamer is sweetened and you like that, you'll need to add splenda or something, since milk is obviously not all that sweet on its own.
