I quit smoking a couple of years ago. As a long-haul flyer, quitting has made my life more pleasant. I used to think about connection times in terms of grabbing a smoke. In general, my MO used to be to smoke as much as possible before a flight and then ASAP after the flight. On trans-pacs I would use Nicorette or the CVS brand, which I actually preferred.

Now I am nicotine-free.
