TRUST ME you will be so glad you did. Tell yourself when you have that urge that your not going to let something like a cigerette that has no brain and is not living, control you!! You are stronger then that cigerette....so don't let it win!
Use your competitiveness(spelling ??) to not let that thing outsmart you. It will be tough especially that first 3 days but keep telling yourself it will get easier and that now that you have started you DON'T want to have to start over again(it does not get easier each time you try to quit) so stick with it THIS time.
Think of your loved ones and how much they want you to quit....if you don't think you can quit for you...do it for them...just be sure and do it.
Last but not least, how much do you spend on smoking? DO tell yourself and DO spend that money on YOU, rather it be fishing equipment or maybe you WHERE smoking enough to pay for a boat.
Keep at it....you can do it and you will be glad you did.
By the way, hard candies can really help with the hand to mouth habit. Even suckers can really help those first few days.
