Obviously, the best cure the next day is more beer.
However, that crash will come eventually even if you allow yourself a cheeky couple of flagons in the hope of a softer landing.
So, what do you do?
My formula is the following:
1. Water and Vimto. 2. Food. 3. Sauna and Steam. 4. Copious amounts of water, Vimto and food for the rest of the day.
The only problem with this remedy is that you're feeling so brand new after getting out of the sauna that you're already thinking about getting right back on it.
