I just started Celexa and have had horrible insomnia followed by heart palps at night and horrible anxiety. When I was on Effexor for 3 weeks, I got the same thing. Is Celexa better and will the insomnia go away with this one? Are Effexor and Celexa similar which is why I'm getting the insomnia? Being up at 1am when I have to get up at 6 for work is no fun and it almost doesn't seem worth being on anything. Please help :(
