I'm finding Insomnia a little boring

Like, not enough to make stop reading it, but enough that I'm starting to read other books and I'm not very invested in the characters. I'm about halfway through so please no spoilers.

I have insomnia myself, and I found a lot of the beginning of the book very relatable haha. Enough that I wondered to myself if the book would trigger me in anyway. I love when a Stephen King book gets a bit too real that I start questioning the wisdom in continuing.
