Currently I am dealing with my own bout of insomnia, worried as heck that it could be SFI, but I got two restful nights sleep wednesday and yesterday though with the slight help of unizone, I thought about it like this, look up every one making a topic about this disease, I gaurentee you there are 100s of people online making post about this disease or having it.
Yet zero reports of any one actually ever having it since one lady back in 2005, who seemed to already have a bunch of other things going on, numerous surgeries etc. I go on google.com and search the news for this disease nothing, and if you are a minority and young <30, your odds of having this disease are almost 0. Even if you are caucasion your odds of this disease is extremely low. Think of the powerball, its like winning the powerball twice back to back then being struck by lightning afterwards.
If you put this in your mind it should make the anxiety of this disease much easier, and while I still require unizone to sleep, previous no medications were really working, not zzzquil, not even a strong muscle relaxer would help me sleep because my mind would race, this disease is so rare that if you dont have the genetic link, its possible it doesnt even exist in the SFI form at the moment and thats all you need to think about. Just my helpful info.
