Hi all, I have been going through the vaping on and off for quite a while. I smoke 3 packs a day. I started with a pen type years ago, wasn't satisfied went back to smoking. Tried a cheap mod with 18mg of nicotine, it burns my throat infact one inhale and I had a huge coughing fit. I switched to different levels of nicotine had same effect, not as harsh as I stepped down to find the best level I could tolerate. I went to a vape shop explained my problems, they suggested a fuchi mod, and not sure of the tank. Started me at 18mg of nicotine again, they claimed it would be less harsh with a good mod and tank. Wrong, had the same experience I had before. I dropped the nicotine level to 3mg which is what I can tolerate, but I find myself vaping constantly with no satisfaction. Need help want to quit smoking, and enjoy vaping!!
