My roommate has been smoke free for about 3 months, according to him. Apparently, the transition was a lot less traumatic for him. He said he was grumpy for the first few days (I didn't notice), but that was about it.
When I asked him what motivated him to quit smoking, he said, "I was tired of running my life around cigarettes." Basically, he was tired of having to worry about buying them, timing his next smoke break, etc. No big inspiration, medical scare or anything. He was just tired of being addicted, so he quit. Amazing.
Interestingly, that freedom from the nagging of addiction has also been one of my most unexpected, yet cherished, benefits of quitting.
Have a happy weekend, everyone!
