Just over 5 years ago I finally quit. When you first quit smoking Einstein relativity of time concept is immediately put to test. First hours, then days and even months seem to drag on very slowly because your brain is deprived of the most important daily routine that makes you feel normal.
As more time goes by it starts speeding up and you are back to normal and the need to smoke is gone. The only mantra from the early quitting days that remains forever is NOPE - not one puff ever.
Good luck everyone. Believe in yourself. Cheers
