 [ Symptoms ] does drinking two or more diet sodas each day make women gain weight [ Disease ] i am sorry to hear you are 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 do not 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 is 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 not 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
