"i have been on and off of antidepressants my whole life. i have been on lexapro for a year and it helped tons. i don&#039;t feel depressed anymore but it seems that i don&#039;t have a range of emotions.  i always seem somewhat subdued, not able to cry, don&#039;t get very excited about anything. i have trouble falling asleep and actually getting good sleep. i guess because of that i am often tired during the day. the sexual side effects are irritating. i gained a little weight but i also quit smoking so that may have had a part in the weight gain.  on a positive note, i am not so overwhelmed with worrying.  i can concentrate much better at school. my irritability has lessened. i feel sane again."
