How about this as an alternative approach? There’s a userscript that puts a time limit on how long you have to answer each review question. If you take too long it automatically marks it wrong.
I’ll be honest, I haven’t used it myself but this may be worth a test to see what effect it has.
On the plus-side you’ll have much faster review sessions - no agonising for minutes at a time trying to recall the answer. The downside is that you’ll likely have more wrong answers per session. But they’ll come up more frequently again if they fall down the SRS levels and hopefully get more reinforced in your mind.
