"I’m still smoking. Much less than I was, but smoking none the less.".
You are winning in other words. And the demon cigarettes hate that. Smoking will take your success, turn it against you, try to drive you into a circle of despair where the only way out is to continue to smoke.
To come anywhere near to winning this battle, you need to understand yourself, your motives, your strengths and your weaknesses. All of the battle is yours alone. Vaping will be a vital ally in helping, as will your family. What they cannot do is step into that void inside your heart when you reach for that cigarette to fill the gap. To those who don't understand, it is the most lonely place imaginable. Vaping can nail the addiction, and NRT and vaping both contribute to that, but the key IMO to success, is staying on the "giving up" wagon. Until you discover the emotional and psychological triggers for yourself, where your limits are, tobacco will have the upper hand. It will lie, deceive, manipulate and pull every dirty trick in the book until it consumes you. Tobacco is ruthless, and you need to be more cunning, and dedicated than it is, to win.
You need to ask yourself two questions, and be brutally honest with yourself in your response. Firstly, why do you smoke? Secondly, can you, in all honesty, see yourself as a non-smoker? Once you have the answers to these two questions, you can plan your strategy and act accordingly.
I've cut my habit down to less than a ¼ of what I used to smoke (40+ years smoking with asthma, COPD and heart conditions). I'm under no illusions that the very last part of the battle, letting go totally, will be the hardest. I still see smoking, to a much lesser degree than before, as a friend, an ally. I need to cross that rubicon, where vaping is my best friend. Daily, my trust in a hot coil and a set of charged batteries grows. Hanging around these forums helps me to understand I am not alone. Soon, the tourniquet around my addiction will cut off the blood supply enough for it to rot and fall off. That, I'm 100% convinced of. My challenge is not to look back, but to look forward. Undoubtedly, I will spend the rest of my life a vaper, but I'm happy with that and can live with myself. I will still need a crutch, but it will be on my terms. I've always admired the folks that can have the occasional cigarette and walk away. I'm aiming for that. Being honest with myself, I don't think I'll ever reach total abstinence, but who knows? What is critical for me is that I don't fall into the hellish spiral of giving up tobacco, patting myself on the back, then falling back into the habit days, weeks, months or even years later with all the associated guilt and shame. The tobacco demon then has an even greater emotional hold over me. Those days are gone.
Some have equated giving up smoking to the grieving process. I totally agree, it is like getting divorced, or indeed loosing a loved one. I believe as smokers and ex-smokers, until we address the emotional side of addiction, we only have part of the cure.
