To all:
Best of luck on quitting!! I did it cold turkey 4 years, 2 months, and 25 days ago but who's counting. I am very proud of myself and my family is thrilled. It's the best thing I ever did for them and myself. As a 30 veteran Firefighter, every fatal fire I've been too was related to careless handling of smoking materials. So you will be living in a much safer environment. I applaud all your efforts it will be worth it!!!! As far as the technology check out the attached link, it should answer your questions.
