Good drug rotation for raves

Raver here. Would love to roll every two weeks or so.

So what are your recommendation in terms of drug rotation. I would rotate so that I can minimize addiction or tolerance to a certain drug.

I love MDMA and K is also good.

So something like: Week 0 - MDMA Week 2 - K Week 4- MDMA Week 6- K

And so on.

Suggestions? Feel free to recommend similar drugs to them
