The primary reason I quit was changing location from overseas back to my home country (that happens to have stricter laws). That change in environment and habit was powerful. However I never really read or learned anything formal on quitting, never discussed it much with friends and never really reached out. It was something that could have easily gone on for many years because, frankly, I enjoyed smoking when I did. I was a heavy smoker. Many times I read threads on TGP about smoking and a lot of it stuck in the back of my mind especially the persuasive arguments of going cold turkey and never looking back. I wanted to say thanks and pass the baton on. If you smoke and want to stop, it's easier than you think. I recommend going cold turkey and avoiding the use of nicotine gums, patches and E-cigs. Save your money. The physical addiction is not necessarily the hardest part - for me it was being around other people who smoke and you enjoy smoking with. Next time you go for a holiday or have a break away from smoking friends, stop smoking and on return change habits with those people. They will stay friends and hopefully be inspired by you. You are just not going to join them for a cigarette. You will find a whole new social group (of hanging with non smokers) expands out of exactly that anyway. I also recommend getting back into major lung exercises like running or swimming and type a post like this if your hands get fidgety! Good luck and be healthy!
