FW, I'll tell ya... I started to vape on a Sunday night, late. This is after smoking 1 1/2 P.A.D. for 26 years. Monday, I smoked 13 analogs. Tuesday, 6. Wednesday, 3... and with one left in my pack, I handed it to my co-worker (Archon here, I think... he just got a Riva, lol), and said to him, "man, you want this? I don't think I need 'em anymore".
Most of it's in your head at this point. It's just a matter of sticking to the PV long enough to *prove* to your subconscious that it WILL work in the place of an analog. No matter how long it takes, just stick with it. Eventually, the craving for analogs will probably just burn out (pun intended) on its own.
Along the lines of Firehorse above: Do yourself a favor. After at least a week (preferably two) without an analog, go bum one. Let us know how long it takes for you to scrunch up your face, gag, and put it out. Then tell yourself, "They *always* tasted like this". You'll never want an analog again.
