well its been about 3 weeks sine i got mine and haven't smoked a normal cig since and i've more than covered the cost of my regular smoking budget with about a month's supply of liquid left
now i hardly even use it compared to when i used to smoke, hell this morning i had 3 doubles with heavy pepper and didn't even feel to smoke after, i sh1t you not
i went from 10 ~ 12 cigs a day to about 24 puffs on my e cig (approx 6 pulls per smoke four times a day)
now i'm breathing a little freer and feel a bit more energetic during the day (aka a reduced state of pulling stones in work

)
a few other benefits :-
* i don't have to wash my hair as ofen
* my clothes don't smell of smoke
* i can smoke in a/c in the car
* ohh smoke scent in the car is fading since i got me e cig
* i don't have to worry about cinders flying back in the car and burning my upholstery
* hell fall asleep with it in you hand, yup lie an bed and puff knowing you wont start a fire
* i vape right in the motherf*&kin living room, thats right
downsides :-
it takes some time getting adjusted depending on how you smoke (for eg if you used to pull hard the vapor hit you strong etc etc etc) but not long before you get teh hang of it
only side effect i got was dry throat one morning (solved by increasing my daily fluid intake)
have to go back and check ecigtt for the red bull flavour or a chocolate even
and no i don't support the prius
