Way to go Don and Hal! You are about over the worst of it by now...
A few things I have noticed from our patients at this stage:
Coughs: as your lungs heal (some 600M alveoli) the Cilia start grow back the little ends that are wiped out by smoking. Seems that a cough starts and you will start to cough up old gunk.. I suppose that is a good sign but sure hear a lot of complaints about the issue.. get something to suck on, seems to help
Friends: Funny but friends that smoke make it a lot tougher.. we sort of "advise" to avoid them as the temptation to smoke "just 1" is going to be awful, if they do not respect you enough to give you some room without the stimulus, well....
I took Hal's route, cold turkey..... sure is nice to be smoke free... (and it bought my new bike)
