I've been taking Lexapro 5MG for about 1 week now and the first couple of days I've could feel some what of a difference. I used to have racing heart, sweats, and couldn't eat anything without throwing up. The only thing I'm still having problems with are unwanted thoughts that I can't seem to get rid of and depersonalization and derealization which cause me to worry more and depressed. Will these things go away? Thanks
