While I've personally never had issues with sleeping, I know someone who was having them almost everyday. This is of course anecdata but in their case it was trying to make plans for the next day while in bed trying to sleep. It was causing anxiety of planning every night leading to poor sleep. The solution we eventually arrived at was to not plan that late. They weren't going to stop planning for a hectic day anyway so might as well flesh out the plan earlier in the day and clear the mind.
