I weaned myself from caffeine many years ago by switching to Caffeine-Free Diet Coke and restricting my coffee intake to two cups in the morning.
I no longer have the crippling panic attacks that I went through with frightening regularity.
I'm hoping vaping works in a similar way to my tobacco habit. For the most part I'm vaping but I still have a cig or two daily.
I can't let go of that damned crutch yet.
I cant understand how you can. I would not get a puff from a cigarette whatever they give me. In the street my wife did not have a lighter asked me to ask someone. I lighted her cigarette I would almost twrow there. Try to increase your nic level. And always think How the ones you did not smoke helped you to good health.
