Sanchez,
i have anxiety and ocd, so when I was talking it, I didn't really notice a change at first, but others around me did. I was much happier and carefree. I found the capabilities to stop obsessing over certain things (ie, having to clean house constantly, having to sleep with the tv on, having to check the lock on the door before going to bed). Also, I had some dizziness that cleared up. I'm thinking about going back on it because i'm having some trouble with the dizziness and my anxiety is starting to get out of control.
For me, it calmed me down and I was able to function without so much worry. I still had worries, but they were not as severe or I didn't think about them constantly.
Hope this helps! Lexapro did a great wonder for me; hope it works for you too. It takes at least 2 weeks for things to start changing, though, if it is going to work. Ask your doctor how long you should wait before you decide to try a different medication. I would think a month, but i'm not a doctor!
