Congratulations on quitting smoking (again). I did the same exact thing: quit and after 15 years stupidly started again for 7 years. Just quit again last summer, about 5 months ago.
Quitting sure doesn't get any easier, does it? Kicking the habit this time was a lot harder than the first time. But it's great to not be smoking and to be taking care of myself (somewhat) again!
Glad you made it too!

Mike PS Good luck with your liver; it's one of the major self-healing organs, and not having to filter out all the pesticides and poisons in cigarettes will help a lot, I bet --
