I have a couple that I LOVE and I would vape them till I couldn't smell them any more, which I hated. Then I went into a local store and was told that some people have three cartridges with different flavors in each. Vape one in the morning, another one in the afternoon and the third in the evening. I started doing this and I haven't desensitized my nose to any of them. I have Cinnabun (cinnamon bun) in the morning, Peanut butter Cups in the afternoon and Papa Smurf (blueberry/strawberry) in the evening. It would be nice to mention that the last 2 were made by Flavorz By Joe. I can't get enough of them. Yeah, I have the nicotine addiction and the habit, but now it tastes/smells great too.
