People do notice whether you're smoking or not. First day back at work and two people have said well done on not smoking – they noticed that I'm not stinking as I used to!
And on a really positive note, a smoking-buddy of mine has started his quit. He was asking me before Christmas how I'd stopped and left with the usual "I'll think about doing that" (we all remember saying that, don't we?). Well, he started on Champix yesterday, said he'd seen me do it and made the decision to stop (he did seem relieved that I hadn't weakened over Christmas). I've told him about this forum, and that I'm available when he wants to rant, whinge, moan or whatever.
So, as well as me stopping the damn things, I may have helped another person in deciding to be free of the ciggies. I feel really good about that, but also a bit more pressure/ encouragement not to fall back into being a smoker.
