Yeah, anyone I know who's been successful has done the cold turkey thing. Telling yourself you don't smoke helps compared to telling yourself you can't have one. If you are really killing for one there's stuff you can get to ease the cravings enough that you can make it for the next few hours. You're not weak - this is a social, psychological and physical addiction. Also, in my experience bad habits cannot just be stopped. They have to be crowded out with better stuff. When you do that, you don't miss the old habits the same. Otherwise, they just come back again. You can do it Purple!
