I bought power-nap which promised to restore 6 hours of sleep in 40 minutes and it worked for most people but not for me. Perhaps I'm hypnosis resistant? Or perhaps I'm just too stressed (which i am). I'm 15 years old and i sleep like 9 hours and still wake up tired for school that's why i need something like that.
Here's the link: http://www.powernap.com/store/cart.php?target=product&product_id=16134&category_id=248. How can i loosen myself in to accept the hypnosis?
a power nap is just a nap in the middle of the day which refreshes your body.
