Smoked for nearly 38 years. Tried cold turkey, tried patches, tried gum. Never lasted more than a couple days. I got me an ecic setup and by 3rd day stopped smoking. Been 35 days and not one desire to start back up. Sleeping and eating better. Not sweating as much and my attitude is improved. Can do things with out losing breath already. My wife who has asthma says because of no second hand smoke she is better also! Best thing I have done!
