I switched right away. No analogs at home at all, only vape. When I was out, I still had the occasional analog in the beginning when there wasn't any good tanks/RBAs out that didn't leak and worked well enough to satisfy. I was disgusted by it, but it was still better than carrying around a leaky tank, or a fist full of cartos hoping that one of them would work long enough to get me home. Now that I have my Kayfuns, I would have to be very desperate to try to choke down an analog.
