"i have been on lexapro for about 10 days. i noticed it working after about 3 days. my anxiety has completely dissipated. i have had severe social anxiety since i was a very young child, to the point that i just didn&#039;t speak most of the time. i battled with it for over 30 years on my own, thinking this was just the way i was. finally, a new job and career caused my anxiety to sky rocket, rendering me unable to do my job properly. since starting lexapro i am now more free and less self conscious. i am talking to people comfortably and enjoying socializing a lot more. i don&#039;t snap at the children and don&#039;t sweat the small stuff. i haven&#039;t gained any weight (or lost any) and i just feel more like myself. the only downside: tired all the time."
