"i was on 10mg of lexapro for 6 years for post traumatic stress disorder. it worked great! i wanted to see if i could have a good quality of life without it since i did gain 40 pounds in that time.  i am on a weight loss program now since i had to go back on lexapro. withdrawal wasn&#039;t too bad. it took 4 months and i was off of it for 4 months. had new stressful things to deal with and that&#039;s why i am taking it again. it&#039;s a great medicine i feel, just have to watch your diet!"
