I read about it in Maxim magazine a few months ago. My friend ordered a few bottles online to try, and our experiences were quite pleasurable. The initial effects are the most interesting and fun. It's just a general sense of distorted existence and reality, some light hallucinations but nothing breathtaking. I felt as if the universe was made of cotton and everyone was filled with air. After we had some more, we were just basically drunk. But that was fun too.
I suggest you give it a try, it's pretty fun stuff.
