I'll give you my best piece of advice (I'm at the 6 month without a smoke point right now). It's something my brother told me when I quit. I asked him why he never started again after he quit 15 or 20 years ago. He said
"Because, quitting sucks and I'm only going to go through it once. If I start again I will have to quit again. It might be a Dr telling me I have to quit, my wife telling me I need to quit, or me deciding I need to quit, in any case if I start again I'll have to quit again and quitting sucks, so I only want to go through it ONE time".
It was a really simple words of wisdom, but every time I walk by a smoker and it smells good, or find myself wanting one at night or in the morning, I think of what he said, and so far its kept me away.
Good Luck, good luck to all of us!!!
