"i&#039;m 15 years old and i have taken a wide variety of antidepressants. i find lexapro to be one of the better ones. i take 10mg of lexapro and it does alright. i have noticed a 10  pound weight gain on about 1 1/2 months of taking this. from my experiences with antidepressants, i do not like them. this is my 4th antidepressant and i just can&#039;t find the right one."
