I just passed out and fell halfway down my stairs. When I came to, I tried to pick myself up and get to my couch. I don't remember when I started to pass out or how long I was out (as in minutes not hours) and finally woke up. I don't remember getting to my couch... I think I hit my head and face (nose) because as my body awakens, it's telling me my neck and face are in pain. I also felt like I had to seriously go to the bathroom and realized there that I had gone some in the fall. This has never happened to me like this. I'm trying to decide if I should stay awake for a while or if it's safe to sleep.
