Why? Because I could. I'd not done anything until that point, and I was going through a pretty dodgy time... and on our way out for a night out, a friend said, "btw, we do this, and this is our bit of peer pressure to get you to do it too." He meant it light-heartedly, but he didn't have to talk me into anything... I was eager to give it a go.
It was amazing, and in all honesty, I can see why people get addicted. I've never felt as amazing as I did while on those pills.
Sometimes, I even wish I could go do it again. It took all my worries and fears away, and I was just happy and content and confident.
