I'm a latte drinker!
At Dunkin Donuts, there's no SF syrups. So you can only get a plain skim latte with splenda. However at Starbucks they have 5 sugar free syrups, a chocolate one (haven't tried) SF caramel, SF vanilla (my favorite), SF hazelnut (good) and a SF cinnamon (not a cinnamon fan). They also have the samefive flavors at any Seattles Best, since they're now owned by Starbucks.
I don't have a machine to make my own lattes, that might not be good for me. A small latte is 90 calories or about 1 cup of skim milk. Even a large one is only 160 calories or a little less than two cups.
