Also tell me that once prions start accumulating,one gets noticeable symptoms probably within few months or atmost 2 years,isn't it? I have known that most people who developed this disorder reported sleep disturbance as the first sympton,which became severe within months..but do u think ( After reading my originalpost and my reply to saeahsweets), that i might have got prions?? i know SFI affects 1 in a million..but still not sure that i am safe.
