I was at a friends house this past Sunday night. We had been sitting on the couch, watching a movie and talking. We dozed off for about 20 minutes and after waking, I decided it was time to go home. Before leaving, we went into here garage to have a cigarette. I smoked mine, put it out and was talking to her while she was finishing hers. I started to get light headed and dizzy. At first, I just thought it was from the cigarette. Next thing I know, she is trying to wake me up. At first, I thought I was in bed asleep and someone was trying to wake me. A minute or so later, I realized I was laying on the concrete floor of here garage. She said that I had stumbled and fell over. My body went stiff and my eyes were open, but I was unresponsive. After a few minutes, I felt fine and have been ok since. This is the first time anything like this has happened to me. Any thoughts? Siezure or did I just pass out?
