I have been taking Lexapro 20mgs. for over a year and then gradually reduced to 10mgs, then 5mgs and went cold turkey. Within a month I first started feeling depress and lonesome and started crying. Then, I had difficulty falling asleep and developed fear of sleeping which would cause me not to live a normal quality of life. I also am afraid that lack of sleep will kill me and hav become a bundle of nerves. Is this a normal withdrawal sympton from not taking Lexapro. I immediately started resuming 10 mgs of Lexapro and will go back to 20mgs soon enough. How long will the Lexapro take to go on track?
