I have always felt like my sleep habits were weird. Somehow they weren't right. I would not sleep at night, and instead sleep a lot during the day in a series of naps. During high school, this was each class period, followed by a nap after school.
Recently I have had a hard time falling asleep until 2, 3, or 4 in the morning. Then I would sleep until 12, 1, or 2, followed by a nap around 6 or 7. I've become so frustrated by it that a few months ago I went to the doctor requesting a sleep doctor. First we did a blood test and determined I was vitamin D and B12 deficient. So I started taking supplements and then got another blood test. With that, everything was normal, but my sleep habits had not changed. So I scheduled an appointment with a sleep doctor.
Yesterday, I took in my sleep journal, told the sleep doctor everything, and answered all his questions. Then I got the diagnosis.
Delayed Onset Sleep, or Delayed Sleep Phase Syndrome
"...is a neurological sleep disorder in which a person's sleep/wake cycle is delayed with respect to the external day/night cycle. The person is unable to fall asleep until the wee hours, typically somewhere between 2 am and 6am, and sleeps correspondingly longer in the daytime, often well into the afternoon."
So now begins the treatment process. We are going the natural route, trying to adjust my internal clock using habits and light to move the clock up. It's going to take at least 3 months to change the clock. If it works though I will be living a normal humans life schedule. That would be amazing. It would be the first time in my life that I feel like I can live like a normal person and not be tired all the time.
