Cotinine Test Preemployment

I have looked high and low everywhere on the internet and on this forum but can not seem to find the answers to my question.

For the nurses who smoke and had passed the cotinine test, how long did you go without smoking a cigarette before testing negative?

A little background:
I am a ppd user for 15 years
I weigh 110 pounds

I have the test next Wednesday and have officially quit for two days now. I really want this job and if it means I have to quit for good, I will do it!
