"for the first week on lexapro, i felt weird; a little lightheaded, dizzy, had insomnia and some minor stomach issues but i stuck it out and i&#039;m so glad i did. i have been taking it for 5 weeks now. i take lexapro around 10am now as this helps prevent insomnia at night. i feel more energetic, happier and more social. i don&#039;t feel out of control or strange or anything. no side effects now. i would highly recommend it anyone to try this."
