With SSRIs there are the 'Zaps'. Erm describing them I would find rather difficult but if you get them you will know them. Feels like being dropped momentarily. They don't last too long a couple of weeks tops and i didn't find them particularly bothersome foreither Paroxetine or Fluoxetine.
I just got off my Celexa. I tapered off of it slowly over about two, two 1/2 months. I did have some side effects. A little "crabby" but mostly just dizzy at times or some "zaps" I think the way I tapered off it worked well. I have gotten off of other medications with much worse withdrawals. I think it depends on the medication and how you are getting off of it. Celexa wasn't bad to get off of Paxil was terrible.
I have your answer but first need to know the following:
Are you switching from one medication to another? If so what meds are you swapping?
OR are you going off your antidepressant with no switch? If so what medication?
