I have been reading this dialogue for a few days, and for myself would say, it didn't come easy, (not a lie) Why because I didn't have enough knowledge of the Nicotine factor in cigarettes, at the time and my self belief was not strong. There are so many confusing issues surrounding NRT The Medical profession for one advocates you use NRT this is a big deciding factor, why this is I cannot say except to surmise, that they think, you might get too aggressive in the process of quitting cold turkey
I used Champix, albeit one per day and none at night, the difficulty came when I had to let go of the champix, it was the thought more than the actuality. I hung on for a week more than I should have because of this. Finally when I let go and went cold turkey, things weren't as bad as I imagined. I did find that I would be quick to temper at times, but I had to work on these things and change my view on various fronts without destroying my fighting spirit so to speak.
I don't think whatever method you choose warrants an overzealous approach to helping another. Something will resonate within the knowledge presented for each individual person, but our own little voice is perhaps the best one to decide when and how. I was at odds with this dilemma simply because my niece (who is a health professional) and a beautiful person as one could ever meet was still using gum while I was home free. There was no desire to help her by telling her to stop the gum, or hitting her over the head. I had noticed she only used the gum at odd times, like a safety valve for her own stress levels. She is an adult, and has ceased smoking the cigarette which includes other chemicals like Tar, this in itself shows me although it has taken her quite a long time, she is committed to not smoking the cigarette.
