"miracle worker.  took about six weeks to start fully working and the side effects were not so pleasant at first.  now taking 20mg daily, i have no side effects and feel great.  during the first few weeks taking it, i would have extremely good moods that almost seemed imaginable and then i would go back to feeling sad.  then eventually that went away.  one negative about lexapro is that my stomach isn&#039;t as strong as it was before and a lot of foods bother it.  all i can do is eat healthy and take pro-biotics.  very happy with lexapro."
