Good way to vent: grab a pillow and go to town on the thing. Punch it to your heart's content for a good 3 to 5 minutes and I guarantee the craving will pass.
Here's a few ideas that can help in the long run:
-Tell everyone (and I mean EVERYONE) you work with that you're quitting smoking and to get on your case if they see you doing it at work. Helped me out a lot.
-Get rid of anything in your house that reminds you of smoking like ashtrays, lighters, matches, etc.
-Go out and get one of those Glade plug-in things to plug into your wall. Helps keep your mind off of any lingering cigarette smell that sticks around your house, and some of them are pretty relaxing.
