Find an app for your phone/watch that wakes you up at the end of your sleep cycles. When you’re in deep sleep you tend to be pretty still, but when you’re at the end of a sleep cycle is when you typically move around a night. There’s apps that will wake you up when it’s almost your alarm time, but you’re moving around.

Also try to maintain a consistent sleep schedule. Eventually you can kinda figure out your own sleep cycles and try to work with them instead of against them.
