I still have problems, but my life categorically improved once I got diagnosed and treated for obstructive sleep apnea. I focus on things much better, I'm better at juggling tasks, and I'm just nicer to people, or at least my fuse is considerably longer than it used to be. Also I'm sure my wife is grateful that I'm not snoring or gasping for breath every night.
I would highly encourage anyone who can get a sleep study done to do it. Most insurance companies will at least cover the sleep study and sleep sleep apnea can lead to a lot of considerably-more-expensive issues later down the line. It's not very invasive anymore, all they had to do was have me sleep with a pulse oximeter for a few nights and apparently that was enough.
