I bad night terrors since i took celexa (citalopram) for depression, i've been off it since sept and they still happen. is it because of celexa (citalopram)? can i do anything?

Celexa (citalopram): Not likely since it's been that long. Possibly have underlying anxiety or sleep disorders.

"Night terrors"?: Actual night terrors happen in stage 4 sleep -- different from nightmares, which happen in rem. Celexa (citalopram) can definitely increase the number of rem episodes/night -- with vivid dreaming & nightmares. Ongoing nightmares after stopping Celexa (citalopram) can relate to the depression & anxiety still being present, possible alcohol or other substance use, etc. I'd suggest following up with a psychiatrist for help.
