I took sertraline for OCD as recommended by a psychiatrist. But I feel anxiety, nervousness, worry etc. And lethargy(due to which I am not able to concentrate on my preparation.) I told my doctor these problems due to sertraline. He said these will go in some days but still after 2 months these have not gone. My studies are getting affected very badly. Should I continue sertraline or not?? My doctor also told that sertraline does not cause these things. But internet says sertraline may do so. What is the truth??
