Thanks for your replies!
I will probably do another MSLT in the future as I'm very confident that it will yield more definitive results now that I know what to expect. Just wish it wasn't so expensive 
DeathRabbit do you have any experience with SSRIs or antidepressants?
Pretty much every doctor I have been to has suggested them to me due to the sleep disorder/anxiety combo. I even got a perscription for Paxil that I never filled. I just always hear terrible stories about those medications and it seems like the side effects outweigh the benefits. I also hate the idea of being on something that so constantly alters your brain chemistry. At least with with things like Klonopin and Xanax they are out of your system within a day or so and I can decide when to take it/take breaks.
I would love to hear about anyone's experience with SSRIs and antidepressants though as I might reconsider if necessary.
I have been on Paxil, Zoloft, and Lexapro prior to N manifestation, because I was over-anxious/depressed as a teen. Of the three, Lex was the best. Zoloft made me gain 20 lbs in a month, Paxil did all sorts of things, but the worst thing about Paxil is that it is very hard to kick. When you try to quit Paxil, you get horrible brain-fog, brain zaps, terrible REM rebound, etc. All of which when stacked on top of N symptoms makes for a very unfun experience. Of course to be fair, I was on the Paxil much much longer than the other two, but my research of has led me to simiIar accounts of how nightmarishly hard it is to kick Paxil. I haven't experienced any TCAs myself, but my mom swears by anafranil. She says she can't sleep without it. But I have not used any antidepressants specifically as a treatment for N, so I cant speak as to how effective they are. I do have mixed feelings about using SSRIs or TCAs for long term treatment, seeing as I had such a horrible experience with Paxil, but it's just a judgement call based on how well it relieves your symptoms versus the side-effects. One thing I can say is that I am on a mood stabilizer (lamictal) right now to deal with the after effects of my horrible Xyrem episode (It brought back my anxiety/depression 10 fold) and it has helped a lot with the brain fog and overwhelming sleepiness. I'm still tired throughout the the day, no matter how much I sleep. But it's a normal tired, not a "my brains are leaking out of my ears" tired. And that I can deal with, being that it's so much easier to function, even if I'm still imparied to a certain degree. The anxiety/depression however, is still not completely controlled. They started me on Xanax, but I think I might need a slightly higher dosage, as it currently only really takes the edge off. Not that Xyrem isn't a wonder drug for some people, but for me, it came damn near close to ruining my life, and it still might if I am never able to succesfully KO this anxiety issue. My experience with Xyrem was nonstandard, so I won't warn you off from it. However, my Paxil experience was far too common upon investigation, and I believe GSK had some legal trouble because they knew how addictive it was and suppressed the research.
