They are VERY addictive!!!! AND
...you build up a tolerance so you have to take more and
more to get the same effect, AND
you wake up groggy, i.e. feeling like you didn't get enough sleep. (At least, this was my experience.) Hope I helped. Good luck to you. P.S. I you don't think Lexapro is working after 2 months (and you've already upped your dosage) try something else! Take care.
