COMMAS, ARE, THE, BANE, OF, MY, EXISTENCE,

Too many times, I have found myself over-comma-ing during my novel edits, only to have to go back the next day and take away like a billion unnecessary commas. Generally, I'm a comma factory when I'm overtired. I don't know why. I guess I just feel the need to pause a lot when I'm sleepy. 

I do know the rules, but grammar rules seem to be in a constant state of flux, no? And so many novelists take liberties. Cormac McCarthy, for instance. The Road is one of my favorite books of all time. The writing is beautiful. Moving. But dear old Cormac does have an aversion to punctuation - at least in this book. But he makes it his thing. Saying "No!" to punctuation is his thing, and it works. 

Other writers seem to put commas in as they choose, maybe as they feel it, while still others are comma Nazis. I guess I fall somewhere in between. Maybe the point is to not stray too far from the rules and to stay consistent in your own writing. Has anyone else experienced their comma bottom? Have you woken up with a keyboard imprint on your face and a head-splitting comma hangover?
