What are the easiest and most successful ways to quit smoking?

I have set a date to quit smoking here in a couple of weeks..I’m not sure how I plan on going about it yet. I tried cold turkey and it was NO GOOD…i want to try another method this time such as medicine, the patch, acupuncture, shock therapy, etc. I was just wondering which ones were proven most effective and any personal experiences would help a lot as well.
