Okay, so I've been dual using for a long time..about 3 yrs, and what I've found is that I'm smoking about the same amount ( one to two ppd) and vaping in between. I've realized that I'm an "all or nothing" smoker. Have one, and all the rest follow. To be honest, I am so addicted to cigarettes that I smoked all through breast cancer treatment last year, wanting so badly to quit knowing what an idiot I was, but still using them as a comfort or coping mechanism...whatever. So here's my dilemma: I am having surgery that involves the vascular system, and will be tested for nicotine beforehand. In a weird way, I'm so glad that the option of smoking is taken from me. Like, it's a relief...strange, I know. However, stopping nicotine altogether is freaking me the hell out! I am prepared to vape 0 nic, but want to know if anyone went from smoking full time to vaping 0, and how did they do with it? Also, please don't judge or come down on me... I've had plenty of that from family and friends, and I'm probably more in disbelief and regret than anyone could throw at me
