Melatonin

Sleep deprivation is like a slow death to all your system. A person that has a regular sleep pattern just can't understand the internal pain of your system of a person with sleep disorders. It all maybe temporary related to stress, bad choices in food,  or other pain that you have in your body. With some people there is no over the counter sleeping pill that would help. Personally I would start with melatonin. Reasonably priced and it is also something your body produces itself to fall asleep. A lot of people have pain in their system a little here a little there that adds up to restless nights of sleep where only pain pills may give them the relief of a good night sleep.
