I am still buying liquids from vendors and one of my favorite vendors does a very flavorful french vanilla. When I first purchased a 10 ml bottle, I ordered it with 0 mg of nicotine. This time around I ordered it with 18 mg of nicotine because I am just not ready to give up the nicotine yet. They supposedly use unflavored nicotine so I don't know what could have changed the flavor unless it was going from "some VG 15%" to "extra VG 40%". I stayed with their "strong flavor" not the "very strong flavor" since I like to use this by itself. A lot of the other vendors recommend a 50/50 mix but this company does not offer that. Could that be the problem instead of the nicotine? I don't know.
