Anyone wake up fully rested and ready to take on the world and then by mid day early evening your yawning and just exhausted to the point you're about to crash or fall asleep?

This has been happening to me for months. I'm on a sleep aid for spasms and cramping while I sleep. Also flomax for bladder issues, and I was just given Gabapentin for the pain.

My gabapentin is low dose, 1 every 8 hours, twice a day. Before I was on methylcarbinol for pain and also baclofen. This combination didn't work for me. I still had pain and spasms and I also woke up rested and by mid day, early evening I'm exhausted and wore out.

I told my primary and she was puzzled and thought maybe I was having trouble sleeping. So I did a sleep study, full 8 hours in REM sleep and no abnormal brain activity.

What are your thoughts?
