Good for you Molly! Just deciding you want to quit is the hardest first step.
Everyone finds a different way to quit, and no one way works for everyone.
My suggestion is find someone to help. There are tobacco cessation counselors that have a lot of ways to help, and can lead you to one that fits you. Most of these people work for places that do not charge for the service. Dental schools are a common location.
I know we don't always agree on everything, but if you want, I can also help talk you through a few things.
