I had 2 concussions as a 9 year old where I had loss of consciousness and amnesia. After the two concussions, I was diagnosed with narcolepsy, sleep apnea and insomnia. Nothing really helps sleep. Sleep doctors for years have treated daytime sleepiness with Provigil and a stimulant. It certainly was helpful in regard to some aspects of life. Are you seeing a sleep clinic or looking into going somewhere?
