Wanikani gamification can really make you forget your real goals and make Wanikani the goal instead of an aid. Question is - what is your goal? There must be some reason behind letting Wanikani take over your free time, I assume. So that is usually the first step, reminding yourself what was your goal in the first place and then shifting your focus towards the skills that you’re lacking so you could achieve it.
Like others said before me at level 40 you might want to cut on lessons for awhile maybe just 5 a day, or even just do reviews for a period of time if the discrepancy between your kanji knowledge and your ability to actually read is where you stated it is, and find a resource that would deliver the goods in a way that won’t put you in an srs hell, just fill in the gaps where it comes to understanding grammar.
You can find a lot of resources in this section of the forum The Ultimate Additional Japanese Resources List!.
The magic happens when you find the combination of resources that make Wanikani leave the driver seat, as it should, for this to happen you need to spend some time trying out several options and see what clicks.
