I Tried 8 Hours of Sleep Every Night for 4 Weeks and Here's What Happened

But the promises of good sleep were tempting. So, I decided to find a way to get eight hours of sleep every night (or, let's just say, as many nights as possible) to see whether I noticed a difference. Long story short: I did.
