"i was first prescribed it in a psych ward as a prn.  i take a cocktail of sedative drugs through the day and at night including: 90mg phenobarbital, 15mg zyprexa, 2mg klonopin, and 200mg vimpat all at night.  i still have had major trouble sleeping.  i got put on 10mg sonata and the first night it didn&#039;t work.  the second night i laid down and tried to sleep on my own, after about two hours of no sleep i took the sonata and within 15 minutes i was asleep and slept all through the night till i was woke up for breakfast at 8:00 am, oh and i laid down at 9:00 pm and took the sonata at about 11:00 pm.  it works wonderfully for me but i think it has its own effects to each individual user and the meds they are on too. i love it"
