"i went from working nights (3:30pm-12:00am) to working 7am-3:30. i would keep thinking all night and i couldn&#039;t shut my brain off. i have always had problems with insomnia, so much so that some times i would stay up for days at a time. i was prescribed ambien by my doctor and i started taking it at night. it worked. the first time i took it i started hallucinating. i saw two of everything and i couldn&#039;t hold my head up. i woke up and felt fine. so i kept taking it. slowly i started getting very sad as i woke up.  i thought about doing terrible things to myself. after being awake for a couple hours i was fine. this drug made me very depressed. i never abused this medication. i was very careful. effects are different for everyone."
