I'm almost 4 weeks without a fag now. I'd tried a few times before, given up for a few months at a time twice and both using patches. I also tried the Champix tablets, but all I can think is that I had no real desire to quit that time as I didn't even cut down on them. They didn't stop the cravings, and didn't make smoking taste/feel any different. I find patches make smoking really harsh, so I went on them for just a week, and have been using the electric ones ever since. I'm kinda getting addicted to them though tbh, cos I still get real harsh cravings, and the electric ones just make it go away for half an hour like a real fag!
