"i have been on lexapro 10 mg for a little over two months, and i already have noticed that my depression crept back. i recently started 20 mg, about a week ago. i haven&#039;t noticed a difference. i have had severe depression for the majority of my life, and i probably would have killed myself without antidepressants, but i feel that i need to add another medicine or switch. it helps with the anxiety, but the depression is what makes me unable to function. this was a good drug, but i have pretty bad tremors, and i&#039;m thinking i need something more powerful."
