I worked for a drug company with a smoking cessation pill. We did a ton of research, and though I am not a smoker, I very much relate to your challenges. It takes most smokers more than one try before it really “takes”. The research shows that you going about this the right way: asking the question of others, and building social support. Let others know what you are doing, and they can help you on your journey.
B’hatzlacha Rabba, I’m davening and rooting for you
