I purchase the "Silk" brand of unsweetened soy milk. Then, when I'm in the mood for soemthing sweeter, I'll add a bit of Splenda, some vanilla, and a bit of nutmeg. It's very close in flavor to egg-nog. You should be able to find unseetened soy milk around you. And good luck finding products that will satisfy both your needs for good flavor, and good nutrition.
