I was browsing Marketing Examples and saw this creative "relationship starter":

Has anyone tried Hard Ketones? I stopped drinking a couple months ago because I decided I'd just rather not. This makes me kind of curious though.

It doesn't have alcohol and doesn't convert into alcohol. I assume it's something other than ketone esters (which I've tried before), but if it's also just getting ketones in the blood it probably isn't worth it. The "hard" and "buzz" angle is interesting.
