Ha thanks, its more related to an old incubus song than the psychoactive drug...
Anyways,
It makes sense what you are saying - obviously if you a good enough impression on her she will at least be willing to still hang out with you, even if the attraction does wane. And you can just build it up from there again
She did mention that she had a crush on me / all these other signs that she was very attracted to me, so I think I am good there.
On a reverse note, it has been a week since I have seen her and even I am feeling not as attracted, just because I have not seen her in a while. Funny thing. Guess we will see how it goes.
