I feel you. There's only one antidote: time.

• It's good to make a disclaimer to anyone around you at work, family, etc. You will be more nervous and you cold act like an ass sometimes. You can bet on it.
• Don't take important decisions in the next month.
• You will gain weight. Less smoke brings more food cravings. Try to compensate with walking.
• Find something to fill your mouth. I used Liquorice root (helps me also with low blood pressure so it was a no brainer for me).
• Keep on keeping on (cit.). You'll have now and then desire, not need, desire to come back smoking. Compensate that with the thought of being free. Good Luck mate.
