Does this sort of thing happen with any sense of pattern? I took adderall XR for a very short time. It made me an unpleasant person to be around so I do not take that now. But I am just curious does the sort of thing you described over your weekend ever happened before? Is there any sense of you feel it coming but nothing you can do to stop it? Be it feeling down or up? Do you notice a difference for the better while the XR is working?
