I've found shifting my day works really well.
Instead of sleeping at 11/12pm and waking up at 6/7am, sleep at 9pm-ish and be up by 4:30am. It's usually still dark, it's extremely quiet and perfect for study!
Pro tip: a nap in the afternoon really recharges the batteries for another work session.
We recently bought a set and it has been a revelation. Darker, quieter room. Better sleep.
