For a clearer head next morning go for a Port. That's a drink made in Portugal, as opposed to an "Australian Port-finish style fortified wine". My theory is this - better spirit, better grape varieties, fewer distillation brain-destroyers. Bottle's gotta have a paper seal across the cork. Lots of Australian wineries are still making port out of stuff they can't do anything else with. Like Penfold's "Makes You Feel As If You've Been Hit Over The Head With A" Club Port.
And yes, I am a lah-di-dah poncy wine snob. When in camp I will ONLY drink my Cockburn's Tawny out of a PERFECTLY CLEAN Vegemite jar. Sorry, that's how it is.
