I can't drink REALY cheap beer anymore like Old Mil, Pabst, Schlitz, Stroh's, Mil's Best, etc...Had too many in college.
The cheapest beer I can drink is Natural Light but it has to be out of a can that has been on ice in a cooler for many hours.
My "cheap beer" that I buy all summer long is Budwieser 10 oz. cans in reg. & light ($11.99 24/pk).
Andytv, the reason you get headaches on Miller Highlife beer is because it is loaded w/ SUGAR.
