"i have been taking lexapro for about 3 months.  i started off taking 10mg per day but i felt like it wore off throughout the day and my energy level would drop.  my doctor upped the dosage to 20mg and i definitely noticed a difference - my mood doesn&#039;t drop during the day.  i don&#039;t feel sad, i can actually concentrate now.  i haven&#039;t had any side effects, in fact it&#039;s even helped me sleep better.  as for the anxiety, i think it is helping because i&#039;m not as worried about everything all the time but i still feel very stressed out in social situations.  i&#039;m in therapy as well so that might help me learn to control the fear.  life shouldn&#039;t feel so dire and impossible.  lexapro helped me see this."
