First idea that comes to mind: log on to my online bank, make some wire transfers e.g. between my own accounts, and include the message in the wire transfer description. Alternatively, if the message is very long, an URL to it.
Getting access to my online bank requires both a username/password combo that only exists in my memory, as well as a separate authentication by entering a numerical code from a unique list of codes that gets randomly queried on each log-in, so the adversary shouldn’t be capable of forging this message. When my memories are wiped, I will forget the username and password, but as long as I have a reliable way of proving my identity, I can go to the bank and have them reset.
This assumes that I can still know who I “should” be after having my memories wiped. There’s also the risk of me never happening to look at my transaction history to notice the message, so this isn’t entirely fool-proof.

For that you simply add any non-verified message to yourself telling you to look at your bank. You wouldn’t trust that that message came from you, but you’d at least check.
Though if the adversary is aware of this, they can spam me with so many non-verified “look at place X” messages that I won’t be able to check more than a small fraction of them.

Ah, an excellent point.
