Do it! No matter how ugly, messy, and hard it is. Quitting smoking is the best thing I have ever done for myself. You will not understand it until later in your quit and it happens at a different time for everyone, but quitting smoking is freedom. One day it will dawn on you that you are not answering to or consulting with your nicotine cravings for permission to live your life and that day will be the day that you are free indeed!
