Sounds like Green Goblin. Half a pint of strong lager, a blue WKD and a double vodka. Goes the colour of Fairy Liquid. Red Witch is a good one too. Cider, blackcurrant and a double vodka. Both get you bladdered but I tend to stick to beer these days. As for 3 day hangovers I get those if I have more than 15 pints. More than 10 is a 2 day job.
I forgot myself, but it was something about a guide to achieve maximum drunkenness and since you got a three day hangover, it must have worked
