As others have reported, adderall is an interesting drug, but it doesn't seem to be a very practical treatment for social anxiety. First off, tolerance to its pro-social effects builds rapidly, so it can really only be taken a few times a week. And even if you manage to avoid tolerance, its effectiveness seems to be incredibly transient--in my case, I will get about a two hour window of effectiveness, even if I haven't taken a pill in weeks. What's worse, the come down tends to heighten anxiety and make things even worse than they were before. Not too fun.
All that said, when adderall is actually working, it's fscking brilliant. For just a short span of time, it dramatically transforms me. I suddenly become supremely confident, totally comfortable and at ease, and best of all, genuinely enthusiastic about stuff. So enthusiastic, in fact, that if I think of something to say, I find myself desperately wanting to say it to somebody! This is great for an extremely introverted person--it demolishes apprehension, hesitation, and apathy. It also helps for a freakishly weird person like me to open up and unveil my real personality. Adderall doesn't ever completely eliminate my social anxiety, but at the height of its effectiveness it comes pretty darn close.
If it could work all the time, I'd easily give adderall 5 stars. But, since it can't come anywhere close to working all the time, I give it 2.
