Gismo: They call it Hell Week for a reason, you know! It would seem you've discovered that now.
It does seem as though smoking and cigarettes are the ONLY possible thoughts you can have, but it's not true. You are thinking of other things, especially when you take the time to focus on something else, something pleasant.
I'm not a long-time quitter -- 90 days tomorrow, but I smoked for 35 years and quit many times.
With this last and final quit (I KNOW this to be true), I was and am still able to look at smoking for what it really is, what it has taken from me, and what I refuse to let it continue to take.
When you watch someone smoke, step back and really look at them. Do not allow the addiction to dictate the language in your head ("oh, that looks so good", "I sure wish I could have a smoke", etc.
Switch the language to "wow, he/she sure looks sad and pathetic smoking". "It stinks so bad." "That smoker doesn't look like a happy smoker at all". "That smoker wishes he was me -- a non-smoker."
Then review all your wonderful reasons for quitting. Then celebrate your success.
It's simple really -- just don't smoke.
NOPE -- Not One Puff Ever
Keep the faith -- and KEEP YOUR QUIT!
