I'm a freshman in college and my doctor recommended I start taking Zoloft for depression and anxiety. Unfortunately for me, I have two major tests next week that I MUST do good on. I read on previous sites that losing concentration is in fact a side effect, but I'm looking to see how common it is. I don't want to hold off on the prescription if I don't have to.. but as I said before, I can't do bad on these exams. Thanks so much to everyone who answers!
