I've found that it is the preservatives in most Domestic beers that I have a problem with the next morning. If I have three or more Domestics, I feel it the next day. My German-import beers (generally don't have preservatives) don't have that effect. Or as the Warsteiner slogan says - 'Life is to short to drink cheap beer' Actually, it isn't all that more expensive compared to 'premium' Domestics, and it is less expensive than most domestic Craft beers...
