I take Lexapro and love it. I have been on/off various depression/anxeity meds over the past 14 years and found that Lexapro works the best for me. DH can definitely tell a difference when I am "on" my meds. I haven't had any problems, except remembering to take it, so I got myself one of those little "weekly" pill cases (or as my doctor calls it my "grandma box", though I am only 29 and not even a mom yet)!
I still have to deal with everyday stress (work, home, etc) but the meds help me keep get thourgh it without letting it "get" to me. Like everyone said, it does take a little bit to kick in and some headaches, drowsiness, etc is normal at first but should go away in time.
