The promble is that to succeed I think I need short term rewards. And I think stopping smoking is more about long term rewards, but I am not good at those.
Save your cigarette pennies for a month and put them towards something (some piece of shiny bike kit?) you want but do not need, and can't really otherwise justify getting? Or towards a posh and frivolous meal?
I did that over 20 years ago, I put the £1.00 per day
in a draw at work. I wanted to buy bits to "do up" my old Claud Butler 10 speed bike, and was skint.
A good piece of advice I was given FWIW
"The first few days are the worst, you will probably be proud of yourself Well done. Promise yourself you do not want to go through that again. the next days will become easier but the temptation to have just one becomes greater because you "have beaten it." You are only kidding yourself. If you have just one puff after a few days you will be back smoking more than you were before. Each day remind yourself how many days you have managed, and that if you smoke today you will have to go through it all again."
Watch out for other smokers!!!! They secretly want you to fail it makes them feel better. they will keep offering you cigarettes! Avoid them if possible in the begining and situations where habit will remind you of your desire to smoke.
Good Luck
Personally I would just start today no big song and dance, just stop. The more people who know you
have stopped (you are not giving up!)the more you need to prove to them and yourself that you can do it.
