I've long been a huge fan of NAC. Seems to help my entire respiratory
system. I also use two doses a day - anywhere from 500mg to 750mg per
dose.

I remember learning of it from a book titled 'Life Extension' by Durk
Pearson & Sandy Shaw - maybe 15 or 20+ years ago.

They suggested it as a supplement smokers should use and since I'd
been addicted to tobacco decided I should start using it. I'm sorry to
say that I'm still addicted to tobacco. Although I've got the habit
much more under control, I still can't seem to give it up completely.
It's becoming increasingly difficult, sometimes impossible, to light
up a cigarrette in public these days and that helps. I only wish
tobacco had been illegal when I came of age, but back then people
harldly gave it a second thought. Hell, I had some relatives that used
to offer me cigarettes at family get togethers before I even started
smoking because once I turned 16 or so because I wanted to hang around
with 'the grown ups' and not the kids. I guess they felt it would make
me feel more like one of the grown ups - basically it was a well
intended gesture to make me feel welcomed and part of the group.

Besides making tobacco illegal, the government ought to put some
restrictions on Afrin (oxymetazoline) - WOW - I'm sure you all know of
the dangers of using that for any extended period. Well, I keep
running into more and more people that have to hit the Afrin every
couple of hours or they can't get even a trickle of airflow thru their
nostrils. That stuff is insidious.
