I don't think so. I've been in this forum for over 2 years and I don't think this ever happened. The good thing about N is, it makes you fall asleep very quickly. It usually happens within 2-3 minutes so most people simply don't have the time to post anything in the forum once they drink their N. I also doubt they could post anything even if they wanted, because it makes you feel extremely dizzy and you probably couldn't write a coherent sentence anyway. I own N, I'll try to post something once I drink it, but I'll probably pass out too fast as well.
