I have never done it, but I've chased enough tail around the world that I am nearly 100% sure that between money spent (planes, dinners, trips, hotels, etc etc) and more importantly time spent, I'd likely be worth at least 50% more and probably 100% more if I simply hired a girl 2-3 nights a week. Not to mention I'd be in a hell of a lot better shape and my liver would love me.
