So I was able to change my work schedule to the mornings and on 4 days, working 6 hours and only 8 hours the other days so I can study consistently in the afternoon and evening, with more time for breaks and getting to bed right after studying then. If I had more PTO between now and then, I would change more days, but it is all I have. They grumbled at me but I know I need this right now.
I'd forgotten about the importance of breaks, which would make it easier to get through some of the material. Perhaps it will help to keep me from reading the material and going "blah, blah, blah, whatever."

That's how bad it has gotten for when I even can get myself to do it. The breaks will be something to look forward to at this point.
I did not know that about the naps or studying before sleep. I will have more time to implement that in these remaining days. Hopefully it is a matter of better late than never.
Thanks for the suggestions and voices of reason! I actually could not see past the rut or outside of the cycle I had gotten myself into.
