"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."
