Can I have withdrawl symptoms from celexa after 3 days of taking it?

Hi everyone, my doc prescribed me citroprolam or celexa same thing i guess, anyhow i finally decided that i would try it, and honestly after the 1st day i felt happy but had a headache and some nausea, but i said i'm not gonna let that bother me if it's gonna help my depression, so day 2 i took it still had a headache, day 2 not as happy but still better than before, now im on day 3, And keep in mind i been breaking my 20mg tablets in half so i'm only taking 10 mg a aday, but day 3 no more nausea, but i feel pressure in my head and maybe some dizziness, and have now decided, theres not gonna be a day 4 for taking this celexa, i was gonna ask anyone if they knew if i would have withdrawl symptoms being only on it for 3 days at just 10 mg or should i go down to 5 then 2.5 then stop? I really appreciate the help, I seen too many bad stories of withdrawl from ssri's that i'm starting to think it's just better to stay depressed and maybe use some natural herbs and remedies,Thanks everyone And hope you all get better.
