My Kingdom for Some Sleep!

I have been having sleeping problems for what seems like forever. I was falling asleep on the way to and from work. Because of that, I stopped working in June and went to see a sleep specialist. The specialist scheduled me for a sleep study at the end of July, which I have since completed. They called me later that week and asked me to come in to do another sleep study at the end of August (next week). I asked them what was wrong with me and they said the doctor wouldn't talk to me about it until after my next sleep study. Wait, wait, wait. Meanwhile, I can't get any productive sleep, and I can't work. It's driving me crazy.
