I could never figure out why some commercial beers....especially coors, bud, miller....will give me a nasty headache after about 2...sometimes even just 1. When i drink my homebrew i never get them..ever...just a nice clean buzz and i wake up feeling great. Anyone else have the same problem? I mean not that's its much of a problem as o don't care for cheap beer. I'm wondering if the sugar used to ferment cheaper light beers has something to do with this.
