Start with one or the other; That is, don't have a beer, then some wine, then some beer, etc. It's the only advice I can really give you, as I don't think it matters which order you start in, you know?
Though there is a bit of wisdom in starting with the more alcoholic drink first (tends to be wine, but you may have some bomb beer)- it gets you where you want to be a bit quicker, reducing the necessity of further doses of the 'lighter' beverage, which one assumes you follow it with.
