Like, I keep reaching up to the back of my neck to de-tangle my bikini string from my hair. And there's nothing there...Shut up. It's California. You have a bikini under your clothing, during the summer, at all times.
One bad thing I've noticed about habitually not sleeping enough: You don't get that nice "new day" feeling. You don't get the fresh start feeling, or the feeling that it's a new day, after sleeping. It's like one loooong stretch of time with no breaks or beginning or end.
