"horrible aftertaste that lasts at least 8 hours. the taste comes about 5 mins after i take it and that&#039;s when i know it&#039;s working.  otherwise i can&#039;t tell like i could taking another popular sleeping medicine. it&#039;s increased my depression and anxiety. i&#039;m getting put back on my previous medication in three days due to the horrible after taste. it&#039;s chemical tasting. nasty."
