Pound the begeezus out of water. It helps curb appetite, and also staying hydrated can lessen the severity of the "blues" during the first few weeks of your quit. It has mine.
Also - I definitely concur with the low carb snacks. At work, I'm living off of almonds, carrots, and beef jerky for snack options. Besides, high carb, sugary snacks like doughnuts, chips, etc. make for a bad dip crave with me. Same with sodas. I've just had to stop drinking Cokes. They just trigger too bad of a crave. I've replaced my caffeine with straight black coffee only. It helps.
