Anxiety
"I was prescribed hydroxyzine as an anti nausea med  for after surgery. I quickly noticed how it calmed me down. Post surgery bathing was especially anxiety inducing for me. I would take one before getting in so I could handle it. It also was the only way I could sleep otherwise I would be up after a couple hours due to inactivity (surgery was from a sports injury). 

I decided to get another prescription for it as an anxiety medication after having an anxiety attack. I took one to calm down and within minutes my panic was under control. 

Highly recommended for post surgery and the occasional anxiety attack."
