Wow! That sounds so different than my quitting trip. For me, quitting this time felt as if it was almost accidental. I've stopped smoking a few times years ago and remember it being just like you described it mattm, but the difference this time was listening to Alan Carr's audio book. It's so weird that after 20 years of heavy smoking I honestly haven't spent more than a few fleeting moments in the past 2 months thinking about smoking.
mattm, or anyone else that's already quit but are still haunted by cravings, maybe try reading Carr's book. It could be the magic pill that takes away the constant 'hard work' of quitting.
