Think of your addiction to nicotine as a rip current passing through your life. It is a fast moving channel that can catch you up. When you're in it, it can seem like there's no way out. Every part of your life includes thoughts of smoking. Get up, have a cigarette, eat a meal, have a cigarette, smoke before work, smoke at parties, smoke when you're bored or lonely or happy or ... your life is one big smoking area.
You don't have to stay trapped in the grips of nicotine. You can get free of it by following the same steps for getting out of a rip current.
