Ask Daniel #21: To Lena, Jamie, Ernest, Ivan, Krissy, Joshua and Misha

Lena wonders what to do with frustration that happens when she sleeps little. Jamie has acute insomnia every few years, but when it happens, it comes full force. Ernest wonders about a study saying insomnia can make your brain shrink. Ivan asks how sleep restriction and stimulus control work from a physiologic standpoint. Joshua wonders if his insomnia is getting worse. Misha asks how to beat hyperarousal.
