I've now found a failsafe method of hang-over prevention, test-driven on a 10-hour session yesterday. So, a big thank you Jo & Rob, whose magnificent barbecue extravaganza was the test-bed for my personal breakthrough. Whilst the drunkeness levels of my fellow revellers escalated to dangerous proportions, little old me survived relatively unscathed, with sanity and memory fully intact. The only downside to this barrier to hanging is that it involves the ingestion of several hundred kilos of flame-grilled meat. A bit limiting that. Oh, and since it relies on the physical impossibility of one taking in any more liquid due to complete distension of the gatro-intestinal tract by the pressure of the food within... well, it can be a tad uncomfortable at times.
