Has anyone combined ket with oxy? How was it?

Have some real 30s from the doc, and some s ket. I normally do my ox on its own and save the ket for another day to do on its own as I got a fat tolerance to ket. Has anyone combined the 2? What was the high like? Sorry if this has been asked before I couldn’t find anything on this combo. 🙏🏽🙏🏽 much love to all
