Going in for a Sleep Study

I am going in tomorrow night to have a sleep study done because I have been having excessive daytime sleepiness for months now maybe even years but my memory is so poor that I don't even remember how long it's been. Whenever I read no matter how alert I am I still fall asleep. I don't mean that I fall asleep and then take a nap, it's like I fall asleep for just a few seconds and then wake up and then it just keeps happening over and over. When I sit for a period of time and even when I am talking to someone it happens then too. I hope that it makes sense how I explained it. Anyhow, it is potentially dangerous because it has happened when I was driving too so I am finally having this sleep study done to determine if I have Narcolepsy or not. I hope that I don't because the only treatment for it is essentially "speed" or amphetimines whatever you want to call them. I can't take those kinds of meds because I am bipolar and it would only enhance my mania. Hopefully it is just a side effect of my medication but there is the possiblity that I have Narcolepsy because my aunt was just diagnosed with it but I don't know if it is hereditary or not. The only time that it doesn't happen is when I am standing up but otherwise I get sleepy as if someone has just tranquilized me and I am fighting it off. So wish me luck with that. Griffin is doing great and just completed his testing in speech. Both Lisa and I were amazed at his receptive language and how well he answered open ended questions. I sure will miss him while I am at the sleep study because it will be one night and a full day on Friday but it has to be done before we move because I don't know if medicaid will cover something like that in South Carolina. Still no word on my disability hearing, just waiting it out.
