If any of you are trying to quit may I suggest Easyway - www.allencarrseasyway.com
This method is 90% effective
It requires no willpower, no weight gain, no cravings - honestly, I quit with this method 7 months ago, it's like I was never a smoker.
It's essentially like counter-brainwashing as it removes your mental dependency on smoking, so no replacing nicotine with nicotine or struggling with cold-turkey. It really is an easy way to quit, PLEASE PLEASE PLEASE just go check it out, it WILL help you quit for good...I promise.
You can either buy one of the books from Amazon for like a few £'s, or you can attend a clinic - the clinic is the same information as the book but with additional support. Clinics costs about £200 but the book gives you 20% off and they give a full money back guarantee so if the clinic doesn't work you get your money back.
I buy the books really cheap and give them to my friends, loads of my friends have quit now with these books. I swear if I could buy a copy of the book for all you lot, every smoker in the country, I totally would!
I tried EVERYTHING to quit; NRT, Zyban, herbal smokes, E-cigarettes, mouthwash/spray, hypnosis, etc. etc. - I left the clinic thinking 'Yeah, right, that was pointless I'm going to smoke again I know it' but for some reason I just didn't, the need to smoke wasn't there at all and I've had no cravings at all since, it really is strange but totally fantastic to be free too!
