It's really not a problem since you're not working and don't have to keep any specific hours. Go all day and into what you're used to calling night. With all of the sunlight there's no reason to stop doing whatever you were doing. When you get tired, then go to sleep. Don't try and force youre self to sleep at any particular time. If the light really bothers you in the bedroom, a cheap temporary fix is to cover the inside of the window with some tinfoil, it's cheap, quick and easy to remove. Scotch tape will hold it in place for the trip. It won't let the light through. If you see tinfoil in a window up here, 99% of the time it's a new person.
