From original post in this string:
One special note I need to make here. When I say everything you do as a smoker, you can do as an ex-smoker, the reverse is also true for some activities. If you were a recovering addict to alcohol or any other substance before, you couldn't use that substance as a smoker and you can't as an ex-smoker either without a full blown relapse.
There are some things you may be able to do now that you couldn't do before due to physical limitations posed by smoking. You may find that you are capable of doing activities that you gave up years ago because you were too old to do them or they hurt when you tried, and now, without smoking limiting you physically, you may find you will recapture activities you lost in your youth. This is great when it happens. But again, use of a substance you had a known problem with in the past is still an issue as an ex-smoker and will be for the rest of your life.
