The answer is in your question but I know where you're coming from and I have the same problem.
The only real solution is just to ease off the booze a little if you want to stay consistent with women - but that doesn’t mean you shouldn't still be having a good time.
* Perhaps something like for every two drinks you normally have, skip one or have a soft drink.
* Switch to a drink that has a lower alcohol content, some beers are much stronger than others.
* Avoid mixing beer/shots etc. - This can be a killer combo as it can get you drunk much faster.
* Or start the night off pre-drinking in the house or get that buzz earlier on in the night, but you'll will need some etiquette to sober up a little later on when you start scouting for potential HB's you want to take home.
In short, you know you can play the field, the only thing harming your chances will be yourself, so you'll need to consider which has more precedence for that evening’s entertainment - Getting wasted or getting laid.
Nowadays I tend to be more of a social drinker as opposed to getting wasted every weekend, I've even gone out as designated driver for the night TOTALLY SOBER and had some good success but the approach is a little more... exhilarating

- Its all about balance and knowing your limits.
