I have been taking Lexapro for about 4 years now. I went on it due to my anger problems which worked wonders. I have just recently taken my dose from 20mg to 10mg in hopes to wean myself off. I am only taking it as needed. Another words, when I get zapped, I take a pill. I am trying to find out if I stop taking a pill when I get zapped, how long will my head be in a cloud? Also, I gained about 20 pounds on this medicine. Will it be easy to lose the weight when not on the medicine?
