Shimon- with all due respect, I do not think that’s the proper understanding of the MB. Why would the MB need to tell us that “if you want to follow the Rama, make sure to do everything that the Rama says to do”? It seems far more likely that his comment is going on the entire suggestion of the Rama, that the option to drink more than usual and then go to sleep is the proper way to fulfill the mitzvah of ad delo yada.
Plus, the MB is quoting the Pri Megadim who is much more explicit. The Pri Megadim first references the Taz who explains the Rama is going like the shitah of R’ Efrayim that the story of the killing of R’ Zeira is the way the Gemara tells us that we shouldn’t get drunk like Rava suggests. The Pri Megadim then quotes the Pri Chadash that one shouldnt drink so much, just a little and then go to sleep. And then the Pri Megadim finishes off וכן ראוי לעשות which is what the MB quoted. So it’s clear that the וכן ראוי לעשות is going on the entire suggestion of the Rama and not the end of it
