anxiety
"My doctor put me on this for agoraphobia.  Due to high levels of stress associated with having 3 teenagers in the house, as well as one of them with behavioral problems and another with medical problems, my dose has to be upped.  It seems to have NO effect whatsoever once the anxiety hits high levels (and then take it).  If I take my dose of 15mg about 20 minutes BEFORE I know something will happen (such as leaving the house) my anxiety is much lower."
