"i was experiencing some awful symptoms such as chest pains, shortness of breath, and heart palpitations.  even though countless tests showed i was in great physical condition, i found it very hard to believe that such things could simply be caused by anxiety.  i guess i&#039;m a believer now!  i am on 10 mg lexapro and the difference 2 months on this medicine has made is fantastic.  when i once feared i would be crippled by these anxiety symptoms, now i can barely even remember them.  i&#039;m feeling like &quot;me&quot; again.  side effects included digestive problems (went away after a week or so) and insomnia (countered by taking lexapro in the morning).  so relieved!"
