Horrible advice. You have the right mindset, but you don't understand club culture or social dynamics.
I want to mention that the best PUA's in the world don't drink (only Rick H and Craig, that I know of). Why? This is a game of chess. It's strategy. Are you out to have fun with the boys, or are you out to develop a skillset and build a lifestyle? Drinking is counter-intuitive to your game. All it will do for you is help your approach anxiety. If you need to use alcohol as a crutch, then your game is WEAK. I see drunks guys in the clubs all the time... sometimes even my friends. You can TELL they're drunk. They usually act retarded and not cool. They don't act confident... if you THINK you're acting confident by being more direct and social, then you're wrong. Girls can pick out drunk guys FAST, and usually blow them off. Your calibration skills are WEAK when you're drunk, and typically you're not conscious of things like your body language, etc... Remember what your purpose is (to sarge, develop a skillset, lifestyle) when you go out. You can have fun at the same time.
Whoever mentioned holding your drink at your side is bang on. Craig mentions this. Most guys hold their drinks up near their face or chest or whatever... it's like you have a barrier up. Don't do this, hold it by your side.
When guys walk into a club... what is the first thing that they do? Right, you mentioned it, because it's what EVERY guy does... they go to get their DRINK, and then they observe for HB's and ****. BAD. I hate hearing this, argh! OK, the first thing that you do when you enter a club is you MUST make sure you're in set within the first two minutes. Don't go for that drink. You want to get social proof working for you. Open the set, then get her to lock arms with you and walk around the club. Magic... you already have a higher value. Mystery talks about this more, I suggest you read his archives. Use social proof in clubs.
Don't walk around the club/bar HOVERING. If you do this too much, you will stale out the room. Never be by yourself, standing around... if you are, whip out your cell phone and pretend like you're talking to yourself (credit 26). Always be laughing, smiling and having a good time.
Don't wait for AI's to approach. Worst advice ever. Just ****ing OPEN the set. You don't need eye contact or anything. Make sure your body language is right (open over your shoulder, don't lean in, and don't face her too early). Use the 3 second rule... eye contact doesn't matter... if you notice an AI, acknowledge it and enter.
Finally, learn to game SOBER girls. If you're relying on gaming drunk girls, then it's what is called FOOLSMATE. That requires no skill (credit Mystery, again). There is no integrity in that, either.
Man, where did you learn this? No offense, but you guys are really light years behind ASF. =b
Some more advice for club guys: check out Mystery and TD's archives on ASF. Check out some of David DeAngelo's products... Mastery Program, ****y Comedy, Body Language and Ask Me Anything - Meeting Women In Bars and Clubs. These are the BEST PUA's in the world. Model them, and you will become good.
Good luck,
