Between my work and commute I lose like 70 hours of study time a week for my summer job so I can relate. I personally just like do my reviews whenever I can at work. All my breaks and any down time where I won’t get in trouble for being on my phone. Even just knocking out 10 reviews here and there adds up.
The other option that I’m a fan of is just doing it in the morning. Wake up earlier and knock it all out before you even go to work. When you come home tired you won’t have to worry about studying and can sleep. From your post I can’t gather any reason why you have to do them in the evening and rather that thats just what you’re used to.
I personally think that its much harder to read in small increments when tired from work compared to wanikani or grammar study. Thats just me, but I wouldn’t recommend it. Regardless of what you do though, my suggestion is to do it in the morning.
