Welcome to Just answer !
Well, since you are on day 5 of taking half dose , so continue taking it for another 5 days and then start taking half the dose of what you are currently taking and continue it for 7 days and then after that stop the drug completely.
But , you should do this under the supervision of your doctor ... and hopefully you would come off celexa safely without any withdrawal side effects..
I hope this helps..
Wish you all the best..
