Good luck OP, I've been smoke-free for 15 months now and so happy to be 'free' of it.
There are many different ways and everyone is different, so don't be disheartened if it takes you a few tries. This is my 3rd!
1st: Went cold turkey, was fine as not working at the time and every time I felt like howling at the moon I went for a bike ride/run so lost weight too. Lasted 18 months, don't really know why I started again, just had a shit day at work (pathetic, I know).
2nd: Used Champix, again it worked, but 4 days after I quit, my BF dumped me (which left me homeless), which was a tad stressful, so started again.
3rd (now): Have been using Nicotine QuickMist spray, it really helps with a quick solve to the cravings, but again some people may think it is a cheat as still technically nicotine. But I'm OK with that as I barely use it these days unless stressed at work and it's much better than picking up stinking fags ago. 15 months and counting...
It took my Mum about 7 attempts to give up, but she did too.
Just keep at it and you'll get there, and you won't look back!!!
