When you have insomnia, you know the struggle

No matter how much caffeine you cut throughout the day, how well you prepare for bed, or how calming your bedtime routine, it’s still difficult to fall asleep. And when you finally do, you might wake up during the night and have a tough time falling back asleep again.


It becomes a frustrating, exhausting cycle—especially if you’ve been dealing with it for a long time.
