"i have been taking vistaril for the last 6 months. i use it for anxiety and trouble sleeping. it calms me down with no side effects, and when i take it in the evening for sleep i wake up feeling good. i&#039;ve taken multiple drugs for sleep including, restoril, trazadone, and ambien. all of those caused me to have the &quot;sleep hangover&quot;. i would have trouble waking up and would spend the whole day feeling as if the medications just wouldn&#039;t leave my system. vistaril is the best medication i&#039;ve found for anxiety and sleep. it allows me to take a few lower doses during the day and a higher dose at night to sleep. highly recommended."
