My online research and being able to ask questions online of those in a quit smoking community who had been quit for awhile.
How are you going to know how you are doing if you don't know what others have experienced?
Once I got off the patch, I needed to know what to expect.
I needed to know if the nicotine receptors ever stopped calling my name.
These are the same things all new quitters should want the answers to if they are serious about quitting smoking.
