I well remember that awful sleeplessness that plagued me after a heavy binge. And, like you, going in desperation to the hospital to get something ANYTHING to knock me out!! Also the jerking and hearing loud noises when on the verge of sleep that would shock me awake. Additionally I used to experience very horrific images and scenes of devastation whenever I closed my eyes. I hope you are feeling better now. I never want to go through that again.
