"tried the generic version after a few rotations of ambien.  the only thing i disliked about ambien was the weird loopiness i&#039;d get.  read over some journal entries i wrote on ambien and it definitely freaked me out.  i didn&#039;t notice a weird metallic taste when i took lunesta.  the sleepiness also didn&#039;t hit me as hard as with ambien, but it definitely peaked after about an hour and i knew it was time for bed.  woke up fine, no headache and no weird journaling. so all in all a good experience and will likely ask for this instead of ambien in the future."
