New delaying tactic...

counting backward from 50, each number on inhalation or exhalation.

Soon the tension will get too strong and an alarm in my head will sound.

It'll be time to go to sleep, because if I stay up, I'm afraid I'll impulsively grab my purse and head to the gas station for cigarettes.

I'd think that was impossible at this point, more than two weeks smoke-free, 

but if there's anything uncounted relapses have taught me,

it's that I should never underestimate my tendency to overestimate my self control.
