Enter into this quit with the mindset that this is THE QUIT. Not that you will "try", not that you "hope I can". DO IT. Grab this beast by the neck and fight. That is really what a quit is, it is a fight every second of every day. Here is the thing, and there really is no getting around this, only the strong can fight. The weak? They sit there and continue to be a slave to nicotine. Like you said, 45 minutes is an eternity = slavery. You are a slave, an addict. So, will you fight for your freedom? Are you strong enough to face the beast and fight, or will you cower back to the corner and remain in bondage?
This site is full of quitters who finally had enough and decided to fight. Yes, it is EXTREMELY hard. Yes, it will suck. But when you win, when you win the battle each day, that victory is life, and man, let me tell ya, it is sweet.
I am an addict. I will never finish this war. That is ok, because I am learning to win the battle day by day. Jump in, join this war, this brotherhood. YOU CAN DO THIS!!!
