My biggest challenge these days is sleep deprivation. I wake up multiple times during the night, and am often awake for 1-3 hours. Recently I've even had troubles falling asleep when I go to bed, a previously-rare problem. And some days I can't even nap. I get up in the morning just as tired as when I went to bed, and wonder why I even bothered. My brain does not do well without sleep, so I'm forgetting things and misplacing things at an alarming rate. It's the pits.
