"i have severe chronic insomnia associated with fm/cfs. i have been unable to fall asleep or stay asleep for nearly 10 years. tried many other medicines for sleep that didn&#039;t work or had unacceptable side effects. sonata served me well for 5 years. was taking 10 mg to get to sleep and then another 10mg to get back to sleep during the night. our health insurer changed and they will only pay for 1 pill per night. my health and quality of life has deteriorated."
