That was one of the things I disagreed with Carr on, but I guess his book was really aimed at drinkers a few notches back from where I was...I already knew alcohol was poison.
Night was a big problem for me too EIAS....it used to terrify me, and oblivion made it bearable...then when I actually got sober, I wondered what used to terrify me so much...
Good luck with your marathon
