This the route to take, PoshGirl. I tried everything offered in the E-Cig sample pack of 27 flavors, and only flue-cured
tobacco was decent. But once I found Bickford, I began to get the flavor I wanted. Another user here squeezes out all his old cartridges into a fluid mix he calls "melange" (same term used for
tobacco mixes). I do the same and then add Bickford to dominate the flavor. My favorite is Kahlua, as in coffee. I use about three-fourths commercial liquid and one-quarter Bickford when I do this.
My absolute favorite is homebrew liquid and Bickford Kahlua.
You can create quite a flavorful mix using non-nicotine fluid and a Bickford flavor of your choice (I find straight Bickford to be TOO strong). I often cut the mix with vegetable glycerine bought at a health food store and Kahlua liquor. The alcohol isn't intoxicating, of course, and serves to purify the mix and add some light flavor, as well as cleaning the atomizer.
I always like sweet, so haven't noticed anything different. Glycerine is a sweetener, much sweeter than propylene glycol. If it gets in your mouth, you go "yum" instead of "yuck". As you'll read elsewhere, it's safe for diabetics to use.
