With current technology, I think the best you can do is enter a Sleeping Beauty experiment with a 10:1 coin and 100:1 ratio of waking days, guaranteeing you a 10:1 update in one direction or the other, as long as you stay in the experiment. You can even bring someone else along and they will update with you. You’ll lose it when the experiment is over, though.
Like Dacyn says, the best way would be to use mind copying, but we don’t have it yet.
