We’ve all had a sleepless night now and again. Maybe the new promotion, the big move, or your daughter’s impending graduation kept your mind racing. Maybe that burrito you had for dinner wants to fight. Maybe the neighbors are just too loud.

Chronic insomnia has been linked to all sorts of negative impacts on a person’s health from their mental well being to their waistlines.
