"i was prescribed ambien, then later ambien cr, for several years for insomnia.  wow!  just like i&#039;d heard about -- take the pill and 20 minutes later i was out.  didn&#039;t really experience &quot;hangover&quot; the next day, but then i allowed myself 7 +/- hours of sleep.  then, it happened:  woke up one morning and my kitchen was somewhat of a mess but i didn&#039;t remember being up or making tuna salad on toast.  that happened a few more times before i weaned myself off ambien.  haven&#039;t had a good night&#039;s sleep since.  i&#039;ve been prescribed a few different sleep meds but haven&#039;t had any success.  tried otc diphenhydramine (benadryl, motrin pm) with melatonin and began not remembering simple words, appointments, etc."
