Day four of the e-cigarette experiment.

Using an e-cigarette on a tram will get you some dirty looks.

Using it while at your shrink will simply have her say "If you feel the need to show a physical manifestation of the fact that you have the strongest survival instincts of any patient I've ever had, I'm not going to stop you."

Anyway, talked to her about the whole thing and the fact that even though I smoked about twice as much as Rome Girl I've gone without a cig since the start and she's had a few.

"You are not an addict," she said. "You don't have the ability to be addicted to anything. You could probably take heroin and not be addicted to it. That's the way your body and your personality work. Think about how easily you stop drinking when you are broke. Most people who drink as much as you do would have physical and mental problems just going cold turkey. You don't.

You went from five Coca-Colas and seven cups of a coffee a day to zero when your doctor told you to stop caffeine and you had no side effects. You've done the same thing when you decided you didn't want to do hash or blow. That's the way you are.

You like to think you are an addict because your heroes are addicts and American society assumes that anyone who does the things you do must be an addict so you have an easy out there. But don't for one second think you are addicted to anything. You're not.

You simply enjoy things a great deal. "
