anxiety
"I took this after being on Zoloft for anxiety & social phobia. Zoloft didn't work (I was on it for about 4 weeks and it gave me terrible headaches, couldn't sleep, but felt tired all the time). After about 2 weeks of being on Lexapro, I got severe anxiousness and anger and rage. I had it for 3 days straight and my husband told me to call the doc and get off the meds. I also was dizzy all the time so much that I couldn't stand up without having to immediately sit down because of the world spinning. I'm switching over to Efexxor now and hoping that will help."
