Insomnia
"32 years old. Have been taking melatonin about 4 years now.  It works great.  I started off at 3 mg, and now take 9mg a few times a month to help with sleep issues.  I haven&#039;t noticed weird dreams.  What I like is that I fall asleep,and if I had to get up for an emergency(3 young children), that there is no grogginess or medicine head feeling."
