Today is the Great American Smokeout. Please, if you are thinking of giving up smoking, today would be a great day to start.
Drop by the website of the Foundation for a Smoke-free America. While aimed mainly at preventing teen smoking and helping teens to quit, the information there would be helpful to anyone struggling with a smoking addiction.
They recommend getting lots of help to quit and maintain your smoke-free lifestyle. There are 2 hotline numbers that might help: 1-800-QUIT NOW and the National Cancer Institute's Smoking Quitline, 1-877-44U-Quit.
Calling (800) 642-0666 will get you Nicotine Anonymous, a free program based on the 12 steps of Acoholic's Anonymous. ("Smoker's Anonymous" on the other hand, is run by a for-profit company.)
So, give it a try. Reach out for help.
