my doctor took me off zanax because i didnt like the way it made me feel, when i didnt take it i felt more panicked! So she put me on hydoxzine 50mg as a replacement,when i took it in the morning i felt fine,but then i took it right before bedtime because i was feeling anxious again. I woke up every hour on the hour threw the night and i also been having nightmares with it! I'm afraid to go back to the zanax,Can i take the atarax during the day, and maybe a half of zanax at night, so that i can sleep without waking up and without nightmares? I,m dreaming about having panic attacks, someone please help!!!
