Closest I ever came was with the Chantix. It works as advertised, really! I went about 10 days without a cig. One day I decided to bum a smoke from someone. I was soooo looking forward to that buzz, but nothing happened.
I actually got a bit nauseous! I quit taking the drug immediately. I'm a respiratory therapist at a 500+ bed hospital in central Texas. I know what smoking will eventually do to me. Most of my patients are smokers. Some have full blown COPD with less smoking years than me.
Ecigs are the only thing that has ever worked for me. These things are going to save more lives, if people will give them a try.
When I think about it the only thing I have quit is: Stinking, throwing butts all over, making a ash mess, burning holes in things, harming others and KILLING MYSELF, very slowly and painfully.
I nominate the inventors of this amazing device for the Noble Peace Prize.
