Since purchasing my sleep mask, I have slept like a baby all night long. I seriously will not sleep well without my mask. The mask is gentle, breathable and block out all the light in the morning. I feel more rested and alert after sleeping with my sleep mask.
However, I have this tendency of losing things... all the time. There are times when I have lost my sleep mask for a couple of nights at a time, desperately searching throughout the apartment trying to find it. In total, I have three different sleep masks because of this particular ... ah... problem.
So don't blame your bed, the pillows, or the sheets if you're not getting good night's sleep*; Just buy a sleep mask!
*Alright fine. It might be your squeaky bed, your flat pillows and your crappy sheets. But it doesn't hurt to try the sleep mask!
