I was on SSRI's for 10 years and quit cold turkey (NOT the way to do it).
I had withdrawals for a while...nausea, 'buzzing' in my head and extreme ringing in my ears that would wake me out of a sound sleep. It lasted several months for me. I hope since you were on it a shorter time it will not last so long for you.
Have you talked to your doctor about it? Or the pharmacist/chemist? Or researched online? You may find more information in those places too.
Did you switch meds or are you not on any meds now? Are you in therapy? That is really helpful and you don't need meds for it.
I hope you feel better soon!
