What actually happens after 30 days without nicotine

Sleep usually settles by week three. Many people report deeper sleep and fewer 3am wake-ups once nicotine stops fragmenting sleep cycles.

Coughing often increases briefly before it improves — cilia in your airways start working again and clear irritants.

Mood stabilises. The anxiety people blame on quitting is usually withdrawal, and withdrawal has an end date.

At £5 a day, thirty days is roughly £150 back. Most people notice the money more in month two, when it stops being theoretical.

The real change at 30 days isn't physical. It's identity. You stop being someone trying to quit and start being someone who doesn't vape.
