I have chronic sleep disorders. Have my whole life. Have not had formal sleep study, but Sonata 10 mg gets me asleep but I wake up every 3-4 hours during night, so I take 5 mg and then 5 mg. Too many horror stories told to me about Ambien CR (longer sleep, but sleep walking, etc) can t be good. WOndering about long term sleep with Lunesta? I am 64 and have gone to a pain clinic for years. Multiple DJD and disc issues. DOes not help me with sleep issues at all, very painful. Would Lunesta 10 mg help me? I weigh 120 lbs, age 64.
