Best of luck with the giving up dude... it's an incredibly tough thing to do. I am currently on day three without a smoke so I know how you are feeling. For me the toughest time is around 6pm in the evening, that afterwork moment. My weirdest symptom I get is my arms go totally restless, and I don't know what to do with them. I end up doing a bunch of kung-fu punches just to wear them out. Just remember, lot's of people give up all the time. You CAN be one of those people and I'm sure you will be! Good luck!
