I know that quitting is the hardest thing that you can possibly do. I quit in 1982 - pitched the pack into a creek and said, "I quit."
That was not the end of it, it was the beging of a difficult battle.
1 - Mind set. You MUST have the midset that you have and will continue to be a non-smoker. All battles are won and lost in the mind.
2 - Keep busy and change your habits. I used to really love to "light one up" after a meal. Get up from the table and do something active. Walk, chew gum, take up a new hobby . . . change your patterns.
3 - If you associate smoking with alcohol, taper off or quit drinking for awhile. It is hard but do-able.
4 - Drink plenty of water. Water will help flush you system of the effects of nicotine.
5 - Do not worry if you gain weight. Take care of this situation AFTER you have quit for several months.
6 - Keep the mindset. Years after you have stopped, you may still get an urge. It is easily passed off.
Good Luck,
Radnor
