This has happened to me too. Before I was diagnosed, my old pdoc prescribed me Celexa. That day, I drove to Wendy's . When I got there, I went into the restaurant and didnt know where I was or how I got there. The billboard that you order from said words but I didn't know what they meant. I dont even remember if I had ordered food but I had gone to a table and sat down and call my pdoc. She answered and said "You weren't supposed to DRIVE!" I still to this day don't know how I got home.
