HI exiles. How do I fix insomnia?

If you find yourself laying asleep for hours on end, getting frustrated with every minute that passes because now you only have three hours and 42 minutes until you have to wake up for work, get out of bed for a short while.

For 10-15 minutes walk around a little bit, drink a glass of water, get a breath of fresh air outside if the weather is mild. Then go back to bed. If you're still awake 20 minutes later, repeat.
