Hrmm .. 6 star hangover for me on return from my rugby clubs tour to Croatia earlier this year. Three days of "if you're awake your drinking" - I didn't drink any water the whole time, didn't eat much either and slept about 8 hours over the 3 days ....
I got home and couldn't get to work the next day, I was having hallucinations that you get when your brain is critically dehydrated (akin to stroke!) - I should have gone to hospital and got myself on a drip but I sat in front of the TV and drank water until I could face eating anything.
And the TV volume was turned down a lot ....
Never again ... not that level of abuse anyway, I think it was the dodgy coke they put in my rum ...
