First, pay attention to the position you wake up in each morning. Once you’ve noticed a pattern, investigate if the density of pillow you’re using is well-suited to your sleeping style. (Side sleepers tend to need a firmer cushion.)
Next, start plugging your phone in somewhere far enough away from your bed that you don’t end up accidentally spending 20–80 minutes on it each night before you fall asleep.
Invest in a stylish alarm clock that reminds you of simpler times. And if all of that fails, consider reading Goodnight Moon each night (the print edition - not the eBook).
