I make 1 of Bill's recipes that takes both Sweetener and Brown Sugar, and I love the taste of the resulting eliquid. But, as far as gunking up coils & wicks...it's the quickest to do so. I've decided I'll definitely lower the % of those 2 ingredients for my next batch in a week or so.
You may find the same with the Sweetener @ 3% and Brown Sugar @ 2% in yours. Just a heads up that if you can lower the % for 1 or the other, or both, you may not run into the same thing with your coils/wicks.
I was wondering if I substituted the Sweetener with Cotton Candy...
