Help! I can’t sleep

It’s 1:45am in the morning and you’re lying in bed wide awake, dreading how tired you’ll feel when the alarm goes off at 6am and you have to get ready for work. You’ve tried everything from having a warm bath to reliving your childhood with a glass of warm milk before bedtime. Even the boring book that used to leave you drowsy doesn’t seem to be doing the trick anymore. Just when you finally manage to get some shut eye, that annoying alarm starts wailing in your ears, reminding you to get up and set off for the day ahead.
