It sounds like you have sleep apnea disorder. I have the same disorder and am on a CPAP machine now, and I sleep much better. The symptoms are exactly as you described -- tired all of the time despite 8+ hours of sleep a night, decreased motivation, lack of concentration, inability to learn, and the apneas happen entirely while you're asleep so you do not wake up or realize anything is wrong with your sleep except that it is no longer productive. Moreover, if you have gained weight during college, this change can exacerbate your condition. I highly recommend scheduling an overnight study at a sleep lab. It could change your life. Feel free to reach out to me if you end up having the disorder -- my email is [e-mail]

For me, it reached the point where I several times fell asleep sitting up in my office chair -- in the middle of a conversation!
