If you want to cut sugar, but want something sweet, stay away from sucralose, splenda, aspartame.
Some good alternatives are stevia, monkfruit, and the sugar alcohols (xylitol, erythritol, etc). I don't especially like the taste of stevia, but stevia + monkfruit blends aren't so bad.
Sugar alcohols, if overdone, can screw up your GI tract.
I keep a bowl of fruit in the house at all times, and it's time to go to the store when it's getting low. I make it easier for myself to get some fiber with my sugar than to make myself something sweet. It's not enough on its own, but it sure helps.
