I am currently on medication, stimulants, not sleeping pills. This isn't a condition that sleeping pills will help, my problem is sleeping excessively, immediately after work. The past couple of weeks from 7pm until 5pm, and that's not scheduled or intentional, more or less without me realizing it. While that is more than enough in hours, I am still exhausted. Mainly because I am not able to address other things such as eating, exercise, or anything else that would benefit my condition that takes a massive toll.

Medical reasons seem to be a valid reason.

I also have a therapist, who has known of my ongoing issues for several months, and while not a doctor, had suggested that I see my primary doctor and tell him exactly what I told her.
I know that while 50 hours a week isnt excessive, it has become extraordinarily excessive for me. I quite simply am not able to handle all of my needs anymore.
