practice good sleep hygiene; don't eat before bed turn off the tv and lights and implement some routine so that you are in bed at a certain time every night and more likely to fall asleep. sometimes inability to sleep is the result of emotional anxiety and unrest so dealing with the underlying issues causing your sleeplessness might be helpful. if you continue to have trouble falling asleep then you might want to consider seeing a doctor. they might be able to recommend a light sleep aid for you like melatonin or benadryl.
