I have all the symptoms of SFI. I can't get tired or have a deep sleep even when I force myself. I have no hunger at all, can barely feel pain and I haven't been able to react to stimulus, like stress and things like that. I also learned that my
thyroid is over active but that could be from the SFI. Sporadic Fatal Insomnia. I haven't slept since the first couples days in Janruary of this year.
