I started taking Lexapro 10 mg in July, for anxiety. It took about 1 week before I felt it was helping. My main complaints are feeling kind of foggy headed, and sexual side effects. I decided to decrease my dose to 5mg. Most of the posts I see are related to depression. Does anyone take this strictly for anxiety, and does 5 mg help with anxiety. Also, anyone notice fewer side effects on a lower dose?
