I'm 37 now, and I have to finally admit that I am no longer 'down wit da kids' as I cannot hold my drink anymore. It kills me if I overdo it, and I'm old enough and dull enough now to realise that the aftermath just isn't worth it. Well, most of the time
Beer can have a fair old carb content, so can make you high whilst your at it and then low during the night just for kicks and giggles.
1 pint of water for every pint of beer when you get home (or as much water as you can physically stomach), plus a bite to eat. As well as the water helping with the wonderful dehydration (which I am told is the main cause of hangover symptoms), it will also mean you wake up to visit the toilet a few times in the night. On each occasion, you can blood test and do something about it.
Oh, and an alka-seltzer chaser before bed as a preventative can help as well. Or it does me anyway.
I've just cut down on the lantus and (apart from today) that has actually made me feel better. Not that I've had a beer to fully empathise with you, so best ignore this last bit
