"25yr. female. i started taking 10mg of celexa after experiencing severe depression. i was having harmful thoughts, insomnia and anxiety in all aspects of life. i finally succumbed to the fact, i needed to take medication because therapy, exercise, positive thoughts and other outlets were not working. the first few weeks sucked. i had severe insomnia, couldn&#039;t eat and felt ramped up and clenched my teeth when i did sleep. i never had the zombie experience though. but a few weeks later, the world seemed more clear &amp; happy. celexa did nothing for my anxiety, i had to add klonopin, but it worked for my mood swings and depression. i would go on it again if i had to. just remember everyone has different brain chemistry."
