The first thing I noticed was that I awoke with a vivid dream. It involved a marriage scene, some webdesign, sharpeis, and a dangerous waterfall with a hot tub up at the top of it. Let's not go into details here.
But the second thing I noticed was that I felt alot better. I was more tired, when I awoke - but then gradually I started to feel sharper through the morning. I was really surprised at the positive impact it had upon my day. I'm going to try this sleep thing out again sometime soon.
