Movies like No Sleep 'Til Christmas

Lizzie is about to marry by Christmas but the preparations are complicated by her insomnia. One night when she's out driving she accidentally hits Billie, a bartender that also suffers from insomnia. She insists on driving him to the hospital but when they reach the parking lot outside they both fall asleep in the car. Afterwards Lizzie starts to wonder whether it was the company of Billie that finally enabled her to sleep. She convinces him to try again. When they both gets a good night sleep again she offers to lend him money for a bar that he wants to start if he helps her sleep until the wedding. The arrangement works but gets more and more complicated to keep a secret. It does not help that getting to know each other changes other things too.
