I am on Day 2 and 13.5 hours into my quit. I found that following Carr's thought of Final Cig to be great Help. I threw myself a virtual party at the time finished the final cig in a wonderful community that supports me daily. It is definitely a mind set and all about realizing that the urges will pass in only a few minutes and holding onto your resolve and continually say no to those urges!
The first day the urges came in as thoughts:
Just One More
Only One
You Quit, You deserve a cig
Just one more
One won't hurt
I was like ugh No,NO, NO, NO Not gonna do it this time!
