Lunesta
"I've  had sleep disruption for many years. I took Ambien for years, now Lunesta. Gradually reduced from 3 mg to 0 mg, with zero problems.  My mind was clearer. With new severe stress & sleep disruptions again, recently went back on Lunesta. Started with 1 mg, then 2 then 3. Trouble is, now still waking up after about 4 hours, then waking and sleeping throughout the next 4 hours. I also use Belleruth Naperstacks "Sleep"  guided imagery CD to fall asleep and her "General Wellness" $ "Stress and Anxiety" in early morning or Jon Kabat Zinn's "Body Scan" during those 4 hours when my sleep is intermittent. I'm finding that I am sleepy and tired when I get out of bed now at 3 mg & feel overly medicated, yet it isn't working well after 4 hours."
