I was a 1.5 pack a day smoker for just over 20 years. Tried several times to stop un successfully over the past few years. 2 months ago mr Dr prescribed Wellbutrin to help me quit. That didn’t work for me either. After getting an ego starter kit e-cig with some 24 mg nicotine e-juice I’ve not had a cigarette since. I’ve only been quit from cigarettes for 17 days now. But I can can honestly say that the e-cig worked for me from day one. Within one week I was breathing a lot better & feeling a lot better.
