I guess I must have been a "Problem Smoker". When the nicotine was gone,
my problem went away.

When I gave up nicotine, I simply choose not to smoke "one day at a
time" and it became easier for me each day. When I tried to give up
alcohol by choosing not to drink "one day at a time", it became harder
for me each day. My problem was not just alcohol. For me "not
drinking" did not treat my alcoholism. I was uncomfortable in my own
skin before I took my first drink as a teenager and I returned to
being uncomfortable in my own skin after I took my last drink.
Alcohol was my solution for 30+ years and did not become my problem
until my final years of drinking when it failed to give me comfort
before it made me blackout.
