I quit in 2005 with the patches and sunflower seeds. This is what I wrote for someone else on Yahoo Answers about my experience:
"I smoke for 14 years as much as two packs/day and in 2005 I quit smoking and never had a cigarette or crave for it since then. I tried many times before to quit and failed. Here's how I managed to do it. There are four things you have to deal with: Pleasure, Addiction, Temptation, and Habit.
Step 1: (Pleasure)
You want to have a bad taste of cigarettes in your mouth. Buy cheap, non filter and the worse tasting cigarettes you can find. Do that for about two-three weeks. That will increase your desire to quit and your mind will remove the "good taste" of smoking and replace it with this bad taste. I even water and dry non-filter cigarettes and then smoke them. The smoke hurt my throat and that was the last memory I wanted to have about cigarettes. It works even better in the winter when you can smell it as well. It helps a lot to have that memory when you crave for the "good taste of a cigarette".
Step 2: (Addiction)
Lower the nicotine intake, buy lite cigarettes, try to stay on the bad taste as well.
Step 3: (Temptation)
Prepare all your friends and family who smoke and stay away from them for the first few weeks. Start your quiting on a friday so you can be in the house and don't have to see any store that sells cigarettes in the first few days.
Step 4: (Habit)
Change habits associate with smoking, for instance I use to smoke every morning with my coffee (when I start quiting I stop drinking coffee at all because my mind would always want a cigarette when I would see a cup of coffee)
I also use to smoke when I would take my brake from work. So on my break instead of going outside I would go in the break room.
Avoid doing anything you usually do when you desire a cigarette.
Step 5: get extra help with NICOTINE PATCHES.
They will help a lot with the nicotine crave in the first few weeks. With the nicotine patches you will still miss the habit of putting a cigarette in your mouth, and that's the part most people fail when they try to quit, because they don't have the will power. I didn't had the will power either. Don't use nicotine gum. Stay with the patches (Steps 1,2,3).
Chew SUNFLOWER SEEDS for the first few weeks. The constant motion of your mouth can eliminate the wish of having a cigarette in your mouth without having to eat all day long. It helped me a lot actually.
The first 2 weeks are the hardest one. But if you follow my tips even a person with a very low will power can do it.
Don't start the patches until your mind HATES cigarettes and smoking, otherwise you will smoke with the patches on".
For me quiting smoking was very hard. Cold turkey quiting is easy for those who have a strong mind and a strong will power, but for all of the other people, few tricks and a little nicotine help will get you there
Good luck!
