I just started taking Celexa (generic) a little less than a week ago. My life had slowed down and suddenly I was have huge amounts of anxiety. I remember having anxiety attacks as a child but I think I kept myself overly busy as an adult to deal with it. I got really sacred because it was getting hard to function. I am finding similar affects. I feel like the anxiety is worse and I am going crazy. I am getting hot flashes or anxiety surges and am having a really hard time sleeping. I start therapy next week and I am hoping everyone is right.. That it takes time for the drug to kick in. I feel at least a little relieved that others are having similar experiences.
