I was prescribed Klonopin for anxiety and Celexa for depression. I was only experiencing anxiety, but took the Celexa for nine days. Had bad side effects (insomnia, tired during the day, etc.). I just decided to stop taking it since I had only been on it for nine days (mistake). I tapered off the Klonopin (the generic form actually) a few days ago. I have been experiencing flu like symptoms since stopping the Celexa a few weeks ago (headache, nausea, muscle aches). Was wondering if anyone else had this experience and how long did it last? I feel like poop right now and can't wait for it to end...
