BTW - I think people make a diluted bottle - 10% Splendex and 90% PG or VG then use that to flavor their juices because one drop of Splendex would be too much for a small bottle of eliquid.
This seems to be already diluted

I want to fix the flavors on some of mine too. Not just sweetener. I got some flavorings at OneStopDIYShop.com
I'm also going to mix up some 0mg flavors to cut my 18mg juices to 12mg
BTW a good Vanilla ejuice is a great fixer-upper for ejuices you don't like. Adds a bit of sweetness and more flavor. I have one flavor with a burnt coconut taste on exhale - gonna try to fix that up with some vanilla.
