Rceler, I know this thread's old but if you happen to still be lurking about here, did your sleeping problems get better? I've been suffering from insomnia for two months now. I'm also worried about SFI because I keep twitching, having insane hallucinations and panic attacks out of nowhere. My body feels like it's constantly in overdrive, and the most sleep I can get is 3 hours max. It's driving me crazy.
