History of insomnia is 13 years old, going from 8-10 hours in a 24 hours interval to 1-4 hours in a 24 hours interval.For the last 6 months I can't even get 1 hour/24hours interval.Brain just won't go into sleep state, even when it tries - as I'm about to drift into a sleep stage I'm violently knocked out into awake state.
Around a year ago had a polysomnography done showing 6% from TST NREM 3 (deep sleep), and REM was 6% as well, but doctors ignore it because I spend 6 hours in N2 (I was heavily sedated, how can they call that sleep?).Since then my condition got worse, sedatives have no effect on me anymore.
What could cause such severe inability of achieving sleep?
