"two weeks ago i began taking lexapro and it is nothing short of a miracle. although i was told it would take up to three weeks to work, i experienced relief almost immediately, within days. prior to taking lexapro, i was having suicidal thoughts nearly every day. my depression was so severe that it would wake me in the middle of the night, like a sharp pain or intense nausea. i would then lay awake. since i started lexapro, i haven&#039;t had any abnormal levels of anxiety or depression and i haven&#039;t had any suicidal thoughts. side effects: sleepy (take at night), mild nausea, extremely (almost too) mellow."
