I have been reading posts tonight's, just catching up on our 'Nictone free world' and I think it needs to be mentioned that anyway you choose to quit is ok. It's no better to be using a NRT than Champix or believing that going Cold Turkey is the ultimate and toughest way to go. It's all down to each individual and what suits each person and their lifestyle. 'Run YOUR OWN race' (As I have heard Olympians say). We all have the same destination, if you run there in black shorts, green shorts or a pink polka dot dress it doesn't matter- it's simply about getting there full stop.
Best of luck.
