Drugs that give you confidence.
First of all - if you have come into this thread with a negative frame of mind about drugs and are anti-them, then you probably won't like this thread. That's great, I'm not advocating drugs for *everyone*, but I'm saying, in the right situation, they are great for people with mild/severe social anxiety.
First off. GHB (or GBL, which converts to GHB in the stomach). A natural sleep aid, anti-depressant and anti-anxiety chemical found in most foods in small concentrations. I'm no scientist but it does something that produces excess GABA in the brain, producing these effects - similar to alcohol, but far more epic. And GHB is incredibly safe (ONLY when the correct dose is taken) and non-toxic. It also doesn't dilate your pupils so no one can tell you're on drugs - a HUGE advantage.
Every time I've been on GBL (was legal in the UK before 23rd December 2009 and could order online) at a party/club situation, my anxiety fades. My tolerance is high enough so I don't get drowsy - but I DO get the anti-depressant and anxiolytic effects.
I hit the dancefloor on it. Bam. I'm the one standing out and dancing the most freakiest. I go up to a girl with complete confidence. I really don't give a fuck how I look and just flow to the music (I do realize how I look though, and it's not *that* retarded

) with the girl, subtly and effortlessly touching her every where. I usually get instant makeouts on the dancefloor - or I just stare in to her eyes, grab her hand, go sit down somewhere quiet and within 2 mins am making out with her. ALWAYS be the dominant one - anytime she tries to do anything dominant with her body language - DO NOT let her. Grabbing your ass? No. You're the man. Take her hands off and put them on her ass. Say into her ear something like - "I think it should be this way around".
As I said - drugs are a taboo matter, but I really do reccommend that if you do try this substance (or similar substance, but this one is good because it doesn't do anything to your eyes; also DO NOT MIX WITH ALCOHOL, DO NOT REDOSE IF YOU DON'T FEEL IT THAT MUCH), try it home a few times and adjust it to the dose that is right for you.
