It took four full weeks for my body to adjust to Lexapro, and my side effects were brutal......nausea, couldn't sleep, couldn't eat....and other symptoms as well. But, once I made it past that, the effects were amazing!! I've often said Lexapro saved my life, and it's true.
Hang in there!! I know it's hard, but please give it a chance to work. I almost quit taking mine after a few days because i felt so bad, but a friend begged me to continue, and I did. Best decision ever.
Good luck to you all!
