"i am a healthy 21 year old but have trouble getting and staying asleep. i have tried melatonin and i feel it may help me get to sleep but not stay asleep. the other night i laid awake until 5:30 am trying to keep my eyes closed with no luck. so the next day i researched some over the counter sleep aids and unisom had great reviews, so that day i picked some up. i took one at ten that night and started getting sleepy an hour later. by 11:30 i was fast asleep. although i woke up a few times throughout the night, as i usually do, i was still tired and found it very easy to fall back to sleep without tossing and turning for ten minutes at a time. i woke up at 9:00am the next day felling minimally drowsy. i will continue to take unisom"
