I'm also glad to hear and some have had success with this drug but I'm also a bit leery when I hear that some haven't been helped. I know it's different for everyone but for those of you who have had success, at what point did you start to notice a difference? And at what dose were you on? I'm so early in my treatment - I wish I could fast forward and feel better now. Because I don't sleep that well, some days I wake up feeling worse. Is this common?
