anxiety
"Got the prescription of the hydroxyzine 25mgs on a Friday.  Picked up my prescription on my way to work.  I took 1 pill.  I felt great and energetic before I took the pill and probably about 30-50 min., I was in sleep mode.  On Saturday, I took a pill in the morning...  just to see if it was really the new meds that caused me to feel this way.  Yes, same thing happened to me.... I developed extreme dry mouth, extremely tired ( worse than a hangover).  All I wanted to do is go lay in my bed and sleep.  I stopped taking this medication.  I had to work on Sunday evening.  This pill would not get out of my system.  I drank 2 cups of coffee, chugged water...  couldn't get the zombie/sleepy feeling out of my body.  BAD BAD MEDICINE!"
