Clonazepam and reduce stress

hi, i'm a 53yr old female with fibromyalgia. I was diagnosed with lupus in Aug. 05. My dr. prescribed be 0.5 mg of Clonazepam to help reduce stress and to help me sleep. My pain during the night from the fibromyalgia is severe. I still can't sleep at night, more so waking up with muscle pains when I take the med. I've told my dr. about this and the dr. has told me to stay on it. I don't know if it's the med or just ironic. If anyone has had similar side effects, please email me and let me know. ******
