Hello, I am new to this forum and have all sypmtoms of Delayed Sleep Phase Syndrome. I have been diagnosed as ADHD and depressed by many doctors. If my understanding is correct a major component of this disorder is excess melatonin production during the day.
I tried using bright lights in the morning as well as low dose (.5mg) melatonin at 5 pm to no avail. It seems to me that since I usually tend to want to sleep during the daytime hours that light in the morning should be ineffective. It's how my sleep rhythms are related to light patterns that is out of whack, not lack of morning light.
My next experiment is to try sleeping with the lights on. I think that this will trick my body into believing that I have slept until 1 pm like I would usually want to. I hope someone can follow my reasoning on this.
Maybe the bright light to advance phase approach works when someone has a normal response to daylight and darkness, but does not when a person has a shifted response to light.
I am trying this because I took 2.5 mg of melatonin a night for 2 weeks specifically to see if I would feel better after stopping, assuming that this would replicate a supressed melatonin state. Sure enough, it worked. Now I want to try supressing melatonin at night with lights.
Comments and criticisms are appreciated. Thank you.
