Make sure you dont put too much stress on yourself to stop on day one.
It doesn't happen for everyone - even most of us - though I'm not sure I can say that without a quick look over one shoulder

I had NO intention to quit smoking - wasn't why I got a PV - I got one to cut down on smoking not give up.
There is a learning curve with using one of these babies - like anything new, you must give it a good run. You dont smoke a PV, you use a longer slower drag. And if you have crap
juice you wont really feel the benefit until you get some decent
juice.
10 days after I got my PV - I gave up smoking totally because I stopped enjoying it. I had NO expectations other than wanting to reduce the amount of coffin nails I used - I wanted to use 5 a day - the ones I really liked - and get rid of the others.
I still say Im just not smoking right NOW - Im not going to say Im a non smoker because I still use nicotine - and I think calling myself a 'nic user' makes me sound like a 19 y/o druggie lol. I'm neither

I smoked for 23 years (a baby in smoking terms!) and this is the longest Ive been smoke free since I was a REAL non smoker.
If I wanted to have a cig then Id have one - but i just have no desire to have any,
Good luck mate.
