Firstly, you should stop radically or cold turkey. This works well for many heavy smokers and the results of it have been long term.
Second, think of a day you will stop, it can be tomorrow or a more favorable moment, but stop radically because you will have the best chance of success. Only a few smokers manage to quit smoking less each time to finally quit at all. It is unpleasant and not wise to stop slowly because you are actually teasing yourself and maintaining the desire to smoke.
Take away lighters, ash trays, cigarettes and everything that can be connected to smoking. Tell your friends and the people around you that you are quitting and if it is possible find somebody else who will quit with you.
The best way to quit smoking is to also change your drinking and eating habits. Try to eat a lot of fruits, drink a lot of water and stay away from pleasure drinks like tea, alcohol and coffee. Physical relaxation is also very important; if you feel edgy go for a ride or a walk or go swimming. With the money you save reward yourself, give yourself something like a clothes or a CD, or do nice things.
Dont give up!
The best way...
