"i have been on prescription ambien for over a year now. last month, i decided to take a more natural approach to sleep. it was nerve wrecking at first, and i had terrible insomnia. then i started taking melatonin. the first night i got a full 8 hours. as long as i keep a sleep schedule, this stuff is amazing. 
note: take half your dose in the afternoon and half an hour before bed. sleep at the same time each night."
