Looks like plenty of reformed types here, me too gave up in 2001 after 14yrs(I started very young at 14)... sent SWMBO to the other side of the world(Italy)for the 1st month and was on holidays from work this helped greatly not being near any smoke or social pressure.
I didnt drink for 6mths... then a big shock to the system discovered beer taste's horrid!
I used that zyban worked for me, the only side affect I got was mild insomia but being a shift worker Im used to that... other than that it turned me into a health freak I went from a 105kg+(only 5'10")down to the high 70's then gymed it up to 89kg(12% Bfat)now hovering around the 90kg mark after 6mths off with a op on my back(back into it now).
I walk 1-1 1/2hrs a day and gym 6 days a week currently... but that'll change once I go back to work.
They say reformed smokers are the worst, I reckon so, while driving along the hyway I can smell if the car infront has a ciggi burning in it!
I dont think even the death penlty would stop a smoker if they banned it, as they all ready have one.
