By now, you can recite all those tips in your… well, in your sleep, if you were getting any.

You know the drill. Go to bed early. Cut caffeine. Get sunlight at 6am (thrilling advice for a person who hasn’t slept).

Yet you’re still awake. Almost as if the problem was never you.

It’s your environment: light through the curtains and a sun that rises earlier than you want. What you need isn’t more advice, it’s the fix.

Luckily, the fix is simple. ORIGINAL Mask for 100% blackout. And PRO Mask if you want to add unbeatable side-sleep comfort.
