I had horrible side effects from Celexa. I was on it for 3 weeks. I could not sleep, I was so tired. At night, I would see trails of things in the dark. Like if I waved my hand infront of my face, I would see 6 hands. One night I had awful, scary hallucination, which made me freak out all night, couldn't sleep. Just layed there terrified. So I told my doctor to give me something else. I also got very shaky, I thought it was serotonin syndrome. Had all the side effects. My eyes were dilated so much & so many other things.
