I’d look to addicts and alcoholics that turn sober. Their feedback loops are way out of whack from years of drug/alcohol abuse. Yes, you do return to normal. It’s just that addicts and alcoholics cause so much social and legal issues that they bottom out of their psychological issues in a more serious way.

If you are on a drug cocktail that mostly doesn’t let you fuck up your entire life, there will be no major turning point to snap you out of it. Clinically, this is a massive success. They are keeping people from being a complete disaster. However, the opposite of “not a complete disaster” isn’t necessarily “tremendously peaceful and happy life”. It can truly be the murky middle.

It can go on forever in those cases.
