In all honesty at this time Joe, I would stay away from artificial sweeteners, both sucralose and stevia. I can't get in to it publically, but I know I don't and will not be using them. Ethal Maltol mixed at a ratio of 1/4 tsp per 10ml PG = cotton candy. So you could use cotton candy as a sweetener, or reduce the PG ratio to 5ml if not sweet enough. I have also found that a drop or two of marhmallow in 5-6ml will sweeten the liquid without masking the flavour. Same goes with
vape wizzard from Jack, a drop or two in 6ml blends and mellow the flavour quite handsomely.
