"i was on celexa for about 3 months, started with 10 mg. and raised up to 20 when i felt no changes. after going up to 20, i felt constantly tired, drowsy and like a walking zombie. my anxiety and depression only got worse, it caused me to have thoughts of suicide and self harm and i just felt worse overall. my experience on celexa was terrible and i would not recomend this drug at all."
