I Need Advice on Quitting Smoking?

ok. ive tried to quit about 2 years ago. cold turkey. i did it for 2 days and i broke and went to the bar to bum one. and then i bought a pack the next day. lol. so im 24. i NEED to quit asap. ive been smoking for about 7 years, a half a pack a day. i used to be in VERY good shape at one point, and smoking is stopping me from doing activities i used to do. and im still young. right now im on a plan i made up myself, and im sure many people tried this method. one week i smoked and counted how many i smoked per day. it came out to an average of 12. so the next week i smoked 12 day for a week, next week 11, next week 10, then 9, and im down to 8 a day. ive been true to my schedual but afraid it's gonna get much much harder soon. has anyone tried this method? or what else should i do? because after this, I NEVER wanna touch a Newport again. Please help. Thanks =)
