Keep on keepin' on, I suppose. There's a concept known as Last Thursdayism that this is similar to. It says that everything since last Thursday (an arbitrary day of the week, possibly referring to the book The Man Who Was Thursday more than Thor, the namesake of the day) is real, and everything before that is implanted memory. The movie Dark City explores this concept.
Wikipedia used to have a whole article on it, but they've since taken it down and integrated it with something else and added some bizarre claims to it. It's now part of an article on rejecting the concept of the Earth being billions of years old. I'm not even mad, it wasn't a real school of thought to start with, but they're trying to make it sound even more crazy now (they added that "left-handedness is a sin" as if that has anything to do with any of this). So, not gonna link it. They used to go into some detail about how people have justified it. I suppose due to the rise in flat earther theory, they don't want to lend any credence to any batshit insane theories, even though most of us were just pointing them out for funsies.
So, being that Dark City is one of my favourite movies and I've considered that, which is very similar... I feel like there isn't much you can do. Worse, anything you do outside the norm would be recorded as some kind of success by the people running the experiment.
