The first roll was an exploration. You didnt know how it was gonna feel, and you didnt know what to look for.
Was it going to be a cocaine or meth feeling? Was it gonna be a chill opiate feeling? You just sit there, anxiously waiting to feel something, then suddenly the music just flows through you. You feel like getting up and dancing. Talking to people suddenly feels so good. And the touch of a woman felt like silk gracing across your skin.
The next couple times, you'll know how it feels, and you'll just be looking forward to it. It'll still feel generally the same, but the whole exploration aspect of the first is completely gone. I'd say after the first 5 times, is when it aint the same no more.
