So I took one Zoloft and felt terrible. I had chills and felt sick to my stomach. I also woke up that night very dizzy and had this out of sorts feeling in my head. I called the doctor and she said to continue it, but I stopped the day before yesterday. This morning my head felt the same and I felt this weird tingling sensation in my head and a headache over my eyes. Could this be from the zoloft? I was also put under on Wednesday for an endoscopy, could it be from that? It's making me nervous.
