I just started on celexa yesterday, and boy do I feel lousy. My doctor prescribed it for anxiety (I also take klonopin). I am starting on a low dosage, but if this is any indication of how I feel now, I really don't know if I want to keep taking it. I feel "spacey", can't seem to concentrate, feel like I can go to sleep at my desk, and don't seem to care about anything. Does it get any better ??????? I'm also worried about weight gain. My doctor and the psychiatrist assured me that I wouldn't gain any weight, but everything I read seems to say the opposite. Also, the sexual side effects don't sound so great. I just don't know if I want to take this at all. My doctor wants me to increase the dosage in two weeks, but right now I don't know what to do. Help !!
