As a uni student, normally twice a week unless I have coursework due. Last year I would get pretty wrecked all the time, I'd forget something every week or two, made out with loads of women, but never got laid, being too drunk to realise when it was on was a big factor in that I'm certain.
This year I still go out just as much, but I've really cut down on how much I drink, I try to stop drinking when I run out of money, rather than take more out with my card, and I don't drink as heavily during predrinks, unless it's a birthday. Still not had any sex this year, but I've come much closer, ended up in a bed or two, and terrible coincedence has stopped it (1 Girl chundered over the side of the bed)
That's not to say that being drunk is the main cause for my lack of success. I have little game at the moment, I can flirt yeah, but I'm still a bit of a ***** when it comes to making a move, which is the worst part, I'll tell myself all night to do something, and still won't. A friend of mine gets just as drunk as me, but bangs fairly regularly because he has some game.
In my expereince too, most people only get laid due to nights out, that may be because I'm in uni, but all of my friends relationships have come from getting together on a night out.
