hey i like Grolsch! Beck's is a better lager, but i wouldn't consider it swill like Heineken. i'm not a huge lagerhead though so maybe i'm just talking out my butt.
with regards to whisky hangovers yes they can obviously be fierce, but nothing is worse than a cheap beer hangover. if you drink a 12er of Chudweiser not only will you only manage a small buzz, you'll feel like complete shit the next day. one night i drank a 32oz. of Bud Dry (don't ask me why), didn't get a buzz, but wanted to beat my head against a wall the next day. bullshit!
anyhow, lots of water and tea were on my drinking menu today.
