You will be hit with strong cravings, but they only last for 2 or 3 mins. They will
get weaker and fewer. In about 1 year they will be gone. It takes that long to
get all that stuff out of your system. Quit back in '71.
good luck, you can do it.
It's been over 7 years and I still get the occasional craving for a cigarette. I just don't give into it. I'm pretty sure the cravings will never go away all together. Hang tough John. You are doing great!
