I totally get this. The word “momentum” you used in your first post is really the most adequate ; I lost it too with Wanikani and my reading habit, but I guess it’s a learning experience. I have to slowly get back into it.
If you are curious I have all my recommended sources on the first post of my translation thread 
It’s entirely classical Japanese though, perhaps you want to focus on modern Japanese right now ? But there are a lot of overlaps between the two anyways.
Glad I could help
