It kinda depends on the person. If you’re not adapted yet, I’d take a break every 3 days.
Then it should be good every 5 days, so on the weekends.
But overtime you may not need any breaks honestly. I went a whole month on 9 devices with no breaks I believe back in October. If I did take a break I most likely used m8k res, abp, bg on the off days.
Just have to take care of your energy body and nervous system.
