Day 15 after quitting vapingWhat is left is memory

What's happening in your body

There has been no nicotine in your body for nearly two weeks, so a craving now cannot be a request for a missing chemical. It is a learned response. Over an enormous number of repetitions the brain tied vaping to cues, and because a vape goes everywhere, the list of cues is long. A cue that fires and is not followed by nicotine gets weaker. That process is called extinction, and two things about it are worth knowing.

It happens only in the presence of the cue. And it is new learning laid over the old rather than an erasure of it, tied to the place where it happened.

What to expect

Quiet stretches, then a sudden strong craving in a situation you have not yet been through without the device. It can feel like going backwards. It is a first exposure, and first exposures are the strongest. The same goes for an old situation in a new setting.

A craving you have quietened at your own desk can come back at full strength at a friend's place or after a long gap, because what was learned at the desk stayed at the desk. There is no nicotine to miss. It is a memory being tested somewhere new, and each time it goes unanswered it weakens there too.

What else you could do

Each one is a single piece of unlearning still to do, and a finite list feels different from a vague threat. Next to each, write one line about what you will do instead in that moment. When one comes up, open SOS; the minute of breathing is there for exactly this. Afterwards cross it off and note it in the Diary. You do not need to seek these situations out. Researchers who tried deliberate exposure to cues did not find that it reliably helped.
