<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello. I started taking 100 mg Zoloft 2 years ago after losing my mother. For the past year I have been cutting the pills in half and taking 50mg. A week ago July 22 I decided to quit taking the medication because the initial reasons for taking it no longer existed...I wanted my sex drive back as well. The first few days were fine; however I have started getting what I can only describe as quick waves of dizziness... Other people describe this feeling as brain jolts . It is worse today than ever. How long can I expect these awful withdrawal like symptoms and is there anything maybe Dramamine that would alleviate these symptoms? Please help. Thank you so much.  <response>: Hi, Thanks for choosing Chat Doctor. I have read your query carefully and understood that you took Zoloft Sertraline 100 mgday for one year, and then you reduced it to 50 mgday since last one year. Since 1 week you have stopped it abruptly, and now you are having complaint of sudden waves of dizziness. I would like to let you know that you are having Sertraline discontinuationwith Chat Doctor.
