Yup I quite 4yrs ago in June.
seriously, just step away from work, and anything else that will cause your heart rate or pressure to rise.
I would lock myself in the beroom away from people and just make myself watch boring TV and then sleep as often as possible.
weening down is good, but ultimatly once you get to where you are smoking only three or less a day then just chuck it all together.
( a little tip) when cutting back make sure to not inhale as deep, and only smoke a half or a quarter of the cigs ( you get your body use to less nicotine ( the patches wont do this for you and ultimatly you will have to detox to beat it as the nicotine is the addiciting part)
by allowing yourself half a cig at a time then butt it , throw that particular cig away ( as it will have more nicotine in the second half , folow me?) but yet only count it as a half of smoke, so when you limit yourself to say 5 a day, you actuially get ten times to smoke ( 10 halfs equal five) but yet your nicotine intake will drop dramatically, and allow your body to detox a little at a time .
good luck .... if you seriously have any questions feel free to hit me on icq, i will help you in any way I can.
