Honestly, I find enough sweet flavors I personally don't have to add any. And I do like sweets! But sometimes I vape so much sweetness that I have to do a 180! Have you seen my tart at Heart recipe? Poor Caddisfly almost died when he tried it. He said, "Well, u got the tart part right!" It's like I am two people in one! I love candy bars...Oh European, German chocolate is to die for! But I love to eat lemons too, especially when my dad brings me a bag from Florida.No sweetener? Gotta have my sugar fix.,..lol!
