Well, I do thank you all for your replies. Though, I think that much
of the point was missed.

I do not have any problem quitting Zyban. I do not think that I will
have any problems staying off the cigarettes once I quit Zyban.

I am afraid, though, that because I have taken it that I may be forever
banned from piloting an airplane. Or maybe I have to be off the Zyban
for like 60 days and I'd pass with flying colors... But, if I go in
after 59 days, I'll get a big FAILED stamp put on the exam, which would
forever disqualify me from getting a sport pilot license (If that's all
I can get) -- or maybe even disqualify me from getting ANY license.

Some have suggested asking AOPA. Looks like it's a great resource,
regardless. But, it costs $39 to join, and right now, the flight
school has all my money.

But, I do sincerely thank all of you who have taken the time to
respond.
