"IT" was the SK book that really did it for me. Took me three tries to read it. I finally finished by only reading it during the light of day, and only with other people in the house.
I haven't read him since "Tommyknockers" which disappointed the hell outta me.
Clive Barker's my favorite.
I used to love to sit in the dark, with just a book light, and read Stephen King and other horror writers... Feet curled up under me... My parents out for the night... alone in our house out in the boonies...
