"i started to get anxiety when i went back to work. i was prescribed lexapro by my doctor and started 3 days ago.  a lot of the reviews say to keep sticking with it so i plan too. as far as the side effects, i get the nausea and dizziness but it&#039;s not so severe that i can&#039;t function. i do however, feel like i&#039;m constantly zoning out and just staring out into space sometimes. i do notice i yawn a lot too and my lower jaw feels really tense all the time. does anyone else have this problem? i&#039;m going to keep sticking with this drug. there is such good reviews once the side effects subside and your body adjusts to it."
