RBF,
You have the right mind set, and I am glad that you have found this site. We cannot worry about quitting forever, it is too long of a time and too hard to grasp. We can quit today though, which is why we post roll call. It is our daily promise not to use nicotine. And as for the stress, nicotine does not help make situations less stressful. In reality it adds more stress to your life, worrying and planning when you can get your next fix. Although quitting can be stressful, the worst of it is only temporaily. Keep quitting one day at a time and I promise you that it gets much better.
Reach out if you need anything.
Steve
