"i was prescribed 10 mg lexapro in march of 2009 for anxiety. it worked well as far as the anxiety was concerned but i decided to stop taking it in april 2010 because of the side effects--weight gain (i gained about 10 pounds even though i was a consistent gym rat and my diet did not change) and a pretty much non existent libido. this is not a medicine you can just stop taking. my doctor weaned me off by having me take 5 mg everyday for 2 weeks and then 5 mg every other day for a week. the withdrawl symptoms were not bad until i stopped taking it all together. i&#039;ve noticed i&#039;ve been easily fatigued and have constant dizziness, which seems to be worse in the mornings--hopefully it will subside soon."
