I was wondering if any of you have used either Lunesta or Ambien. I was on Ambien for about 6 months and my NS abruptly called me in for a visit...during which he took me off Ambien and put me on Lunesta which doesn't work nearly as well. He said Ambien would make me too dependent...not addicted but dependent. I quess my question is I liked my Ambien (probably a little too much) and I wondered if any of you have used these meds and could comment. I feel like looking for another doctor. I know what that sounds like but it helped me sleep like nothing else. I'm not on anything else besides 75 mg. Lyrica once a day and 500mg Naprosin once a day. NO opiates at all. Have any of you heard of any warnings that have been issued to drs. that would have prompted this. Also I have an L-5 S-1 disc herniation and have had one discatomy w/mild to moderate stenosis.
