Should I bother taking more Kaplan FLs?

Hi guys so I’ve taken 5 Kaplan FLs so far and I’m honestly getting so wiped out and they’re starting to take a huge chunk of my study time bc I lose a day taking them. Is it worth it to keep taking them ? I test in a month and I was planning on taking the 3 AAMC FLs I have left in 2 weeks. Is it a bad idea to lose study time for these FLs or am I making excuses for myself be honest guys plzzzzz. I also haven’t taken a study break since I’ve started studying in June. I test in sept
