What does it mean that the extinction timeline?

Behavioral extinction takes time — weeks or months depending on how established the behavior is.

Example: You quit social media cold turkey on January first. By January fifth the urges have subsided noticeably and you feel triumphant — this is clearly working. By January twelfth, for reasons you cannot identify, the compulsion returns with nearly the same intensity as day one. You open a browser, navigate halfway to the login page, and stop yourself, but the craving lingers for hours. By January twentieth the urge has faded again, and now you barely think about it — until February third, when you are bored at an airport and the old reaching-for-the-phone pattern fires as if the past five weeks never happened. You have not failed. You are experiencing the extinction timeline: initial burst, gradual decline, spontaneous recovery, further decline, occasional resurgence, eventual asymptote. The curve is not linear. It never was.

Try this: Select a behavior you are currently trying to extinguish or have recently attempted to extinguish. Draw a simple graph on paper with the x-axis labeled "Days" (mark intervals from 0 to 90) and the y-axis labeled "Urge Intensity" (scale 1-10). First, draw the line you expected — what you assumed the decline would look like when you started. Most people draw something close to a straight diagonal from upper-left to lower-right. Now draw the line that actually happened or is happening — with the burst at the beginning, the uneven decline, any spontaneous recovery episodes, and any plateaus. Compare the two lines. Where do they diverge most? That divergence zone is where you are most likely to misread normal progress as failure. Finally, project the curve forward: based on what you now know about non-linear extinction, when would you realistically expect to reach your asymptote? Write that date down.
