I'll write a blog post at some point, but the short version is that suspending my use of https://apps.ankiweb.net/ was a serious error. It's so effective that studying without it is almost a waste of time. It flatly solves the problem where a year or two after deliberate studying you can barely remember anything.
The ebook "Anki Essentials" is the nicest intro to SRS I've seen: https://foggymountainpass.com/anki-essentials/
Saves at least a few hours versus the manual + random blog posts.
