I was a smoker for 41 years. I was smoking 3 packs a day. I have tried quitting many times using many methods. Patches, gum, Wellbutrin, cold turkey and nothing worked. My son quit smoking by vaping and a friend gave me a small Ecig to try. He quit smoking by vaping also. A few days later I bought a larger unit using 24 mg nicotine Eliquid and I immediately cut back to 1/2 pack a day. After about 2 months I was able to quit the cigarettes. I know I couldn’t have quit without vaping. I am down to 6 mg of nicotine now. I am getting my breathe back, my activity has risen, I feel so much better.
