It could be both. I do this a lot. I have to rewind movies and tv shows. Thank god I have DVR. I know my meds can cause a little bit of a slow reaction and brain freeze. I also started doing it more after I stopped SIing. I think it might be a coping mechanism. I made up my mind not to SI, so when I want to I just space. It was bad when I was working, having to ask the boss to repeat himself sometimes twice. It's gotten better. I'm taking a not for credit course online to try and retrain my brain to pay attention for school this fall. So far it hasn't been too bad. They offer them at Hillsdale.
