Bella does a little mental arithmetic. Okay, once a month. And we can try to think of something better, in case there is something, but this will get you much improved right away. Who do you want for witnesses so it doesn't look like I just did it without permission?
Yes, I'll make sure I get it all. But you'll be able to remember that you said I could.
Rúmil, I'm going to try something complicated and Miriel needs witnesses.
She can make some of my memories go away temporarily. When she does that, I feel better, but I also want the memories back and I can't remember the reason I agreed to let her. We agreed she can take them away and show them to me once a month, but I'm not going to remember why I agreed, so you're here as proof that I did.
There.
And now -
Opaque.
Bella looks apologetically at the witnesses. I may need help if she decides to follow me around or something.
But I can't live like this I need her to remove it. I want my memories back! I'd rather be sick than have a hole like this in my head!
...Bella decides not to opine that if Miriel can't function like this either because she's too busy begging for her memory back it's not an improvement and she'll undo it anyway. She is silent.
I could try leaving and see if that lets her concentrate on other things. Can you reach Tirion via non-smoke-signal if there's some kind of unexpected emergency?
