I am taking lexapro and was wondering if anyone who has taken it is experiencing what I am experiencing, right?

now I feel a bit forgetful in a haze and like the medicine is annoying and heavy up there. I also don't like that I feel less active and not as alert. Is this the way this antidepressant is? Someone was telling me that they had to take Welbutrin to conteract this reaction is this what I will need to be more alert and active if so I don't want to continue with the Lexapro. Does anyone know if there is something else thats better to take for depression or is this they way they all are gonna be?
