or Escitalopram is an SSRI
type antidepressant which should not be stopped suddenly. It needs to be decreased down in dose and then needs to be stopped. If not you MAY experience withdrawal symptoms
, which in your case, looks like what you have experienced.
I would suggest that you decrease the dose slowly over weeks probably under a psychiatrists guidance. If at all you still have unbearable side effects, even at this mode of stopping it, then you may need it to be replaced with a long acting antidepressant which can be tapered off easily.
Hope this helps. Good Luck
