Have you been practicing as you read it? There’s nothing that says you have to blow your way through it as fast as you can. And if you need a break, then find a similar topic at your level and go for it. S. Connelly has some books that are beginner friendly and she has a different perspective. I bounce between the her and EA for specific things.
Youtube is another source of info. It doesn’t have to be related specifically to demonolatry to be useful, as not everyone follows that specific path. I’ve found a lot of channels useful and can say I don’t agree 100% with any of them. Take what’s useful to you now and perhaps something else will catch your eye later.
BALG/EA’s Channel - https://www.youtube.com/channel/UC3PbU2BsHFjySvk3sdBltpA
Behemoth-X https://www.youtube.com/user/joenunn666 (I really like this Black Flame meditation and often use it as background when at work).

That should keep you occupied for a while. There are a lot of other channels, but these have large amounts of info. Some are more beginner friendly than others, but it’s good to have a spectrum.
