The relevant book is The Maudsley Deprescribing Guidelines Antidepressants, Benzodiazepines, Gabapentinoids and Z-drugs by Mark Horowitz and David Taylor (2024).

This book is for medical professionals, but if you find your doctor doesn't have the relevant training then worth to educate yourself. The TL;DR is that you need to go really slowly in the final steps.

Horowitz also has many talks and podcast appearances on youtube. Example old video https://www.youtube.com/watch?v=LRr09mvMEAU but he has many more recent ones.

I don't have any direct experience with this, but I've been watching my best friend struggle with widthdraw symtoms for many year, and I also know from doctor friends that they are not trained on de-prescribing protocols.
