I used to Smoke, but realized it soon after seeing my Cousin, Who was a Chain Smoker, Had Brain hemorrhage. :(

1) WillPower is the most important thing, You can get Irritated, Depressed.

2) Personally i Disagree that Smoking is a Stress Reliever...

3) OH YES!!! I Feel Amazing, Never ever had an Urge to Smoke again, even with Friends.... :)

Best of luck Captain, Hope to see you in My Boat... :)
