congrats on quitting smoking. i had a massive coughing fit this morning, but still reached for a cig when i was done -- addiction at its' shittiest.

once you get past the first 3 days things should be a LOT easier -- i should know, i've quit about a hundred times.

be careful with bupropion/wellbutrin/zyban, though. aside from being an anti-depressant it is marketed as a stop-smoking aid, but it can have some crappy side effects, like moodiness, severe insomnia or seizures. it's great that you feel it's helping you to quit smoking, just be careful.
