"i&#039;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 &amp; 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 &quot;sleep&quot;  guided imagery cd to fall asleep and her &quot;general wellness&quot; $ &quot;stress and anxiety&quot; in early morning or jon kabat zinn&#039;s &quot;body scan&quot; during those 4 hours when my sleep is intermittent. i&#039;m finding that i am sleepy and tired when i get out of bed now at 3 mg &amp; feel overly medicated, yet it isn&#039;t working well after 4 hours."
