Why did he say "Hoy Mashkimei va'Boker"?
Radak: Woe to those who rise early in the morning to drink wine. Their entire engagement is to drink wine and enjoy meat. They do not engage in Torah and Chachmah. In the morning they rise early to drink, as if they chase wine, to see where they will find good wine.
Sha'arei Teshuvah (1:31): They are fools who do not break their desire, and pursue pleasures.
Malbim: He saw people rise early, and asks why - is it to pray in Beis Hashem? No, it is to pursue wine!
Who are "Me'acharei va'Neshef"?
Rashi: They drink wine at night. Radak - they stay late in the drinking house.
What is the meaning of "Yayin Yadlikam"?
Rashi: The wine burns in them.
Radak: The wine incites them to do all their desires.
