How long should I take Break?

I have been taking edibles daily for like 2.5 years now. I usually take like 30-40 MG (depending on the brands). Right now I’m at 4 days break and just wondering how long should I take the break? Google says 21 days, but I feel more is needed?Whats your thoughts on this? And weirdly I dont have any withdrawal symptoms like insomnia or anything anyone feel the same thing?
