Day 28 after quitting smokingWhat a clinic would call you

In shortStop smoking services in England count a four-week quitter as someone who has not smoked at all in the last two weeks, confirmed by a breath test. You are there. It is a checkpoint, not a finish line, so reread the reasons you wrote at the start.

What's happening in your body

Stop smoking services in England count their results at four weeks. Someone who has not smoked even a puff in the last two weeks of that period, confirmed with a breath test for carbon monoxide, is recorded as a four-week quitter. By that definition this is where you are. It is a checkpoint rather than a finish line, and the standard says so itself, because it asks again at a year.

What to expect

The risk from here has a different shape. It comes less from a bad afternoon and more from a single occasion months away, a wedding, a loss, a holiday. Everyday cravings keep getting rarer, and the danger is that not smoking starts to feel so settled that the guard comes down. It is also normal for the reasons you started with to feel less urgent now that the worst is over. That is a sign of progress, and it is exactly why they are worth a second look.

Try this

Open Settings, read the reasons you wrote at the start, and edit them so that they say what holds today.

What else you could do

They were written before you had been through any of this. Some will still be true. One may now sound like someone else wrote it. These are the words SOS will show you on the day you need them, so it is worth having them in today's voice. If a new reason has appeared, a morning without a cough, a sum of money, a person who noticed, add it while it is fresh. There is room for three, so keep the three that hit hardest.
