I am so glad you posted about Celexa, and would like to share with you my experience. The doctor's directions were to take it at night. The first morning after taking it, I felt like a complete Zombie. So much that I was not effective at work or anywhere else. Unfortunately, I suffered from other side effects including a severe panic attack. After 4 days I quit taking it. Sorry to hear about your experience, but glad to hear I am not the only one. I switched to a different medication and very glad that I did.
