What do you think my chances of winning my unemployment appeal are?

I have an unemployment appeal hearing here in CA tomorrow. I must admit that I am a little bit nervous. I was fired for misconduct, sleeping during business hours. Which I was not doing. When I was fired I was not presented with a document stating as to why I was fired, just my check. I never signed anything when I was fired either. When I asked for such a document I was told by my former supervisor that I would have to speak with HR but said HR person was on LOA. I was also not allowed to see my own employee file. I was told that I could make an appointment to see it but that I would not be allowed to copy anything and take it with me. As I was looking into something else on FaceBook I came across my former SBU manager's page where she was talking with another management person about having a cot in her office for power naps! I did make a copy of this. So I ask what do you think my chances are?
