Hi Jen,
Giving up smoking is easy. I did it lots of times.
A method to implement that resolution I once heard of: Evaluate just how much you spend on the habit.
Each week instead of spending on ciggies place the money in a jar. The jar must be secured by anyone that can stop you from ratting the jar, and be trustworthy ofcourse.
Eventually on a pre- arranged date or amount you get the jar to spend as reward. It can be as little as a month or two at first. Then go longer.
By having someone help you it becomes a little easier to discipline yourself.

Good Luck

Cheers Marty
