I have done a similar thing a couple of times!
Something I am trying to keep in mind, to keep me from going back even just for one, is these few points from the WHO. After…
1 year, your risk of coronary heart disease is about half that of a smoker’s.
5 years, your stroke risk is reduced to that of a nonsmoker 5 to 15 years after quitting.
10 years, your risk of lung cancer falls to about half that of a smoker and your risk of cancer of the mouth, throat, esophagus, bladder, cervix, and pancreas decreases.
15 years, the risk of coronary heart disease is that of a nonsmoker’s.
So every time I have just one, I have to wait another 1+ years until my long term health risks are reduced. And if I don’t cave, then I only have 11months+ to wait (I’m about a month in so far - this number should get more motivational/meaningful as time goes on!)
