It was, but that's not the point of this anecdote. This experience gave me the idea for the premise of a sci-fi story: a drug which, once taken, has no affect on you whatsoever outside of one crucial impact, which is that whatever happens while you're on it, you won't remember once it wears off a few hours later.
The scientific findings related in this article seem to indicate that developing such a drug would be possible. Would people take it? I suspect they would, although I also suspect that it would lead to regrettable behaviour. (That is probably, in fact, its chief advantage.) What about you - would you take it?
Are experiences less meaningful if you don't remember them?
