Escitalopram
"I have been taking Lexapro for years with fairly good results and low side effects, usually between 10 to 15mg, I am a 44 y/o woman, mother and wife of middle school children, my anxiety/depression has gotten worse and I was recently diagnosed with OCD. I tried to increase to 20mg  but after 4 weeks felt lousy tired a lot, poor sleep,  gaining some weight, not much. I'm going back to 15mg,  does anyone really think there is a difference between the 2 doses. I just want to feel happy again."
