My wife, who is suffering from Ovarian Cancer , was under chemotherapy . As on date 5 sessions were completed and one more is scheduled on 20/07/12. After first chemo, as she developed insomnia my oncologist prescribed zolefresh 10mg at night. But unwanted side effects, such as depression , mental inconsistency, unable to think, illusions etc., she has stopped this medicine, two days back. When contacted my doctor he suggested Librium 10mg, which made the situation worst. So she stopped everything. Now she could not sleep continuously at least for six or seven hours. One hour sleep and then one hour restlessness - this continues throughout night. Please suggest remedy.
