"i was on lexapro for about 7 years in doses that ranged from 10 to 20 mg (i altered the dose with permission from my physician depending on my circumstances). overall, it performed well for me and i was generally able to deal with the side effects (the greatest for me: drowsy and difficulty concentrating). about a month ago i decided that i wanted to be drug-free because i am not currently in situations that contribute to depression. i abruptly went off lexapro (not recommended; should have tapered down) and now find myself in an unpleasant territory (volatile; irritable; impatient; headaches). not happy with the new me so doctor has suggested i try celexa (10 mg). will post a review after i give it a try. smile!"
