"i&#039;ve been using 10mg ambien for about 10 years now. i sleep very soundly and awake 6-8 hours later refreshed and loads of energy. not every night, maybe 2 or 3 times a week. it is my miracle drug, but only if i take it on an empty stomach! i too have had some &quot;amnesia&quot; like times. when i first began taking it, i called an ex boyfriend while my husband was asleep next to me. thank god the side effects have gone away!"
