If you have read any of my previous posts, you would see that I struggle with severe anxiety as well as depression. I spoke with my doctor and decided I wanted to try an antidepressant. Last year, I took zoloft (sertraline) for 6 months without a SINGLE side effect. It was working well and then I felt that I didn't need it anymore so I stopped taking it. Since I know it worked before, I wanted to take it again. I've taken it for about 5 days now and the side effects are unbearable. I am having extremely vivid dreams, insomnia, waking up every hour, dizziness, drowsiness all day, irritable, and the worst of all... nausea. I have emetephobia (phobia of vomiting) and the nausea is really unbearable. I am taking zofran (prescription anti nausea) but it barely helps. Now I am anxious because I'm nauseous and being anxious is making me more nauseous and it's a vicious cycle. Should I stop taking it? Wait it out? I just find it so strange that I had zero side effects when taking it last year but I do now.. how does that work? Please help.
