"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&#039;t get the zombie/sleepy feeling out of my body.  bad bad medicine!"
