I have dealt with sometimes crippling sleep problems most of my adult life. 25 years in the infantry isn’t doing my sympathetic nervous system any favors at this point in my life, and as such, sleep is an elusive friend to me.
I can talk for hours about it, but one thing you said stuck with me,
“Adding a lot of sleep is difficult with my schedule”
This is the root of your problem. If your schedule is so jam-packed that you can’t fit in enough sleep, you are shortchanging your brain’s self-repair and indexing systems. Your brain is in “self-preservation mode” in those mornings when you can’t drag yourself out of bed as you stated.
You’ve got to take a good look at your sleep habits and make a real objective assessment as to whether you are taking proper care of yourself. If you’re not getting enough sleep for your brain to do what it needs to you are going to find diminishing returns in your training as well since the real magic happens during recovery, not during the breakdown.
I would strongly recommend you grab an app such as pillow or something similar and track your real sleep schedule for a week or two, then compare it with the National Institute of Mental Health’s recommendations.
I don’t mean to sound preachy, I’m no expert, I’m just a very experienced sleep amateur.
