I bought this as a present for a friend who has trouble getting out of bed in the mornings as a night out. For that reason I think it's good but that's it. You're not going to take this as a practical guide admittedly but reading through it I thought it was rubbish. 2 of the pieces of advice repeat themselves so much and a lot of the advice is just variations. The first half of the book isn't even about beating it but not gaining one in the first place.
In short I'd like to rename the book "How not to get hung over and 10 ways how to maybe beat it, probably not."
