I cannot give medical advice but I have personal experience. My sleep disorder does not have to do with being pre-med.
* Have you been evaluated for other sleep disorders, like sleep apnea, with polysomnography?
* Have you seen a doctor who specializes in sleep medicine?
* Have you considered seeing a
sleep psychologist?
I have had these tests and seen these doctors, for my sleep disorder, which is believed to be due to my chronic illness. Anyways, I am really dysfunctional because of my medical problems, but you might want to try all of those outlets. So far, the sleep psychologist was the most useful as she gave me strategies and brainstormed issues that I encounter that prevent me from sleeping.
Sleeping pills can be a detriment and can cause problems, although they can be helpful to many. I got in to a very minor fender-bender the morning after taking an Ambien, 10 mg pill. I have not "needed" to pop pills after seeing a sleep psychologist.
Also, this book was recommended to me by my sleep psychologist, and it has really high ratings.
