Fuse is really good. So many good drinks out there to drink though. I am a fan of Diet Dr. Pepper as well. I am not a coke fan and really not a Coke Zero fan. I have been experimenting with the various low sugar/carb energy drinks as of late out of curiosity.
Rockstar Sugar Free- Barely made it through the first sip.
Monster Low Carb (Blue) - Tastes like sweet tarts. Not bad, but weird.
Sugar Free Redbull - Same as monster. Monster is better though.
Amp Sugar Free - Is probably the best out there. It is more of a Diet Mountain Dew taste or flavor.
