Yeah I know that feeling! Since i'm on meds I get drunk pretty fast nowdays (I technically shouldn't be drinking... But that would suck!!!) but it's still a large buffer zone between being drunk and being TOO drunk (and ill!). I have a habit of speeding up drinking the more I drink... It's just too easy! Plus some drink is actually very tasty. Last time I was in London though I got very drunk near Camden... And on the tube ride back to Shepherds Bush there was a random metal guy who was drunk too and very cheerful. Offered me some of his Disaronno (That he "liberated" from a shop... Naughty guy) so there I was being wasted with a total stranger in a tube carriage... Everyone else keeping away from us... And I was drinking stolen Disaronno out of a paper Subway cup from a complete stranger!!! Sometimes people being drunk brings out the worst in people... But in this occasion it brought out the best in a couple of strangers =D
