My husband snores horribly. It rattles the walls and sounds like a den of grizzles. I sleep in the guestroom or on the couch. It's the only way I can fall asleep. I spent the first 5 years of our marriage being exhausted from being awaken when he snores. It doesn't matter who falls asleep first or how heavily I sleep. Sleep is a must. A well rested Speckla is a happy Speckla. An exhausted Speckla means an unhappy and stressed Speckla = no good for anyone.
It hasn't gotten in the way of marital relations. It's all good.
