Sign up for cryonics. All of your subjective future will continue into quantum worlds that care enough to revive you, without regard for worlds where the cryonics organization went bankrupt or there was a nuclear war.

Doesn't this mean that you should deliberately avoid finding out whether cryonics can actually preserve your information in a retrievable way, because if it can't it would eliminate the vast majority of the worlds that would have brought you back? Whereas if you don't know it remains undetermined. Am I getting this right?

You're confusing subjective probability and objective quantum measure. If you flip a quantum coin, half your measure goes to worlds where it comes up heads and half goes to where it comes up tails. This is an objective fact, and we know it solidly. If you don't know whether cryonics works, you're probably still already localized by your memories and sensory information to either worlds where it works or worlds where it doesn't; all or nothing, even if you're ignorant of which.

How far do "memories and sensory information" extend? I'm worried about what happens during sleep. It's been argued that dreams are a stability mechanism that prevent self-change, but I don't know if that applies to the external world.

Following this line of argument, our memories could change while we are awake if we aren't actively remembering them.
