I use liquid splenda which has no carbs and I looked up crystal light on other low carb forums - it says no carbs. Here, it says .2 grams per 8 oz. I think both are negligible if anything... but then again, drinking 2 quartes of crystal light can make a dent.

I need to drink water instead of crystal light - sometimes I do. I don't drink enough water in general anyway. I'll try harder - promise.
