I have been on this med for 10 or so days now. I am currently on holiday and I am constantly tired all of the time with such little energy and sleeping for a good 10 hours a night and feeling incredibly drowsy during the day. I have read that this should ideally be a morning drug but I have to take it at night otherwise I am a zombie all day. Is this normal? I didn't think somnolence was a common side effect of sertraline.
