o my goodness, these symptoms are exactly what i have been experiencing lately. i have been working night shift now 7-7a as a RT for about 6 months and i have been waking up to horrible headaches and have been taking exedrin migraine almost every day now which may not be good. my room is not fully dark when i sleep, but its just dark enough i thought, maybe i should make it darker, i drink enough water during my night shifts, so thats not my problem, and then the bathroom is light when i get up to use the restroom during sleep during the day. so , maybe i need to get a darker curtain for the restroom! hmm, gives me alot to think about. what else do i need to do , i really dont want to continue to take headache meds or sleeping meds every day.........
