DY:
Thanks for the citations. Some are accurate, others not quite.
Aruch Hashulchan when addressing yy”sh seems to be referring to drunkenness in a very general sense, and is not talking about Purim. He is not very supportive of the “chumroh” of getting drunk.
Mikdash Yisroel is quite clear that use of other intoxicating beverages is not part of L’ivsumai bePuriah. Read it again. He notes that some people do it, but does not agree with it.
Rivevos Efraim states that other intoxicating drinks are not part of the Purim drinking.
The source for L’ivsumai referring to wine is Rashi in Gemora Megillah.
Many poskim translate ad delo yoda as “ad velo ad bichlal”, meaning that the drinking should not reach that level but just before it. If you read them carefully, they are not being meikil. They are claiming that the drunkeness is a detraction from the fulfillment of mitzvos, and is a state that we should not reach.
