It's funny but I still expect to be hacking up phlegm every morning as a matter of habit. It hasn't happened since I quit smoking. As short as a week afterward, I could inhale, and feel like I could just keep on inhaling for ages. It took me a couple of days to get used to, and was a really sobering reality.
I wish the blessing of that on everybody who wants to quit smoking, so I hope that new smoker follows
through and posts here so we can help him/her along.
