Wolf, kol hakavod. We are not doing yevamos any more as we are not sure we are doing it “for the mitzva”. I am not sure I know people who drink “for the mitzva” also … Given what is going on in our society, not drinking is probably the right thing to do. Even if you personally think you can do it right, you are encouraging others and who knows where they stand.
The question is – what do you do with 4 cups on Pesach? This is a more restricted environment, so my objections above do not hold.
