i'm sorry to hear you're going through this. as an insomniac myself i can very well commiserate with the problems a lack of sound sleep can cause. what you are experiencing is unfortunately quite common. it is not unusual for the brain to kick into high gear and want to continue processing all night long especially after a day of high tension like you describe. because you don't normally have problems sleeping i would advise you start by implementing " good sleep hygiene. " follow these steps: go to bed at the same time every night and get up at the same time each morning use the bed only for sleeping not for watching tv reading or any other activity (except sex) try meditating for a few minutes in the evening to calm your mind do not watch tv or use a computer or cell phone within two hours of your bedtime; these devices emit a spectrum of light that suppresses the body's production of sleep hormones like melatonin do not eat or drink for a couple of hours before bed take a warm bath or engage in some other relaxing activity before bed keep your bedroom cool dark and quiet if you follow these routines for a few weeks and you find you still can't sleep then it may be time to consult a doctor. there are over-the-counter sleep aids you an take but most people do best by maintaining a good sleep routine. wishing you well!
sleeping difficulty due to non stop brain activity. for a few days i've been unable to sleep at night. every time i try my head is overloaded with random sounds and images. i sleep in small starts and i have a mild throbbing headache within a few hours. this started after a day of high tension but my lack of sleep is making my morning life worse.
