"in 2003 i started on (brand name) celexa 5 mg a day for anxiety and depression. within a week i started to feel almost a magical feeling of well being and a nice calmness within myself. the world looking brighter and so much better. for once in my life i felt that the hole in my soul was healing. no more anxiousness and crying most of the time and no more waves of horrible emotional pain. i gradually worked up to 10 mgs a day and now i am on 20 mgs a day. i did have a headache, nausea and loss of appetite. they went away. i gained weight but was feeling so much better. i tried generic celexa for almost 1 month and i felt irritable-like a dark cloud descended upon me. it is not the same as the brand.
