I'm imagining waking up after a night of heavy drinking with
memories gradually returning. Now, you can, of course, condition
everything on the person who will find that he won the lottery. But
making that a hard part of my identity doesn't make sense to me,
otherwise you could not be the same person and forget about it, or
consider being the same person who participated in the lottery who
then went on to win it.
Now,while this boils down to an arbitrary definition of personal
identity, we should be consistent about this; you can be the same
person as the won who had not yet won it, and you could imagine
being a person who did not win it, then you'll likely end up waking
up as a copy in another branch who did not win it.
That seems to invoke a dualism, such that there's only one real
"you"
who may be in different branches at different times. I'd say that if
"you" wake up as a copy in another branch where "you" didn't win,
it's
because "you" didn't win. It's the same as saying the man who sees
Moscow didn't "wake up" as the man who sees Washington.

We can turn this into a reverse Bruno-like problem. If your memory is
temporarily cleared then copies of different branches merge. The
branches will of course be different, but you without a memory of
having won in the branch where you did win is the same you as the you
in another branch were you did not win where you also have forgotten
about not winning.
Actually, there will objective evidence as to whether or not you have
won the lottery. There will be a winning number and you will have a
ticket that will have this number on it or not, regardless of whether
you forget anything or not. The idea that branches in the MWI can
recombine after the relevant quantum measurement has been irreversibly
recorded is nonsense.
There is no recombination of branches here, it's just that you become
identical to another version of you located in another branch. Then,
upon a new measurement, you'll spit over the different branches again.
If somehow you would not be identical to another copy of you located on
a branch where the outcome of the lottery is different, then that means
that you actually did not forget the outcome as the information about
the outcome is still present in your memory (the algorithm that defines
you).
