I had been on Celexa for about 6 months in combination with Ativan some nights to help with anxiety and sleeplessness. I was still feeling very up and down with mood also still suffering from anxiety. My doctor had me stop taking Celexa and start on Zoloft 5 days ago and I am experiencing worse depression. Just wondering how long it will take for this to subside and the medication switch to balance... Thank you.
