I often can’t sleep. It can take me hours to get to sleep at night, even actively trying to think of “nothing” or the usual tricks like counting sheep. If I’m woken up I often can’t fall asleep again easily.
Which is why I’m up at 5am. I was awoken by the puppy’s alarm. She was given a small clock to simulate her mother’s heartbeat but her chewing it keeps bumping the alarm switch so it went off.
