Diet Sodas are completely sugarless... and zero calories, to boot. The only thing is, they contain sodium and potassium... if you're not careful, if you drink too much soda, your sodium levels will go up. Moderation din ang kailangan.

Coke Zero actually tastes more like regular Coke than Coke Light... but it seems to be on the sweet side (a little bit sweeter than Coke, but not as bad as Pepsi Max... ugh...). My wife says it has less aftertaste than Coke Light, but the "new" Coke Light has very little aftertaste compared to the old Coke Light anyway.

I prefer the Coke Light blend. less sweetener, more of that caffeine kick... which is the one reason I prefer Coke over Pepsi. Honestly... softdrinks taste like crap. I only drink them for the caffeine buzz...
