I was able to quit by using Nicorette gum (2 mg) whenever I had a craving for a cigarette. Once the smoking habit is gone, you sort of forget to chew the gum. It worked for me and is worth the investment. I still keep some gum around just in case I’m ever tempted (like when I’m around smokers or have been drinking)
As an incentive, keep a “piggy bank” of cash that you would have spent on a pack of cigarettes (so for example, in my state cigarettes are $7 a pack and I would smoke about 1 pack every 3-4 days, so every 3-4 days I would put $7 in the bank. Then, when you have quit and are totally free of nicotine… take that money and buy something cool for yourself as a reward.
Good luck… be one of the 5% who actually remain non-smokers after quitting! It is hard, so you should be proud of yourself when you do. Who wants to be a wheezy, yellow, wrinkly, stinky old person anyway?
