To cure insanity? That doesn't work. Insanity cannot be cured by large doses of niacin unless the insanity was caused by pellagra, a disease brought on by niacin deficiency. (I sincerely
hope that this is a joke... and if it is, or even if it's not, please don't say stuff like that withou making it clear that it's a joke -- some people won't be able to tell that it's a joke, and that could lead to niacin overdose if those people try to cure some thing or another with niacin). (Apologies of I'm being too serious or over-the-top about this -- I just don't want anyone to get the wrong idea and do something detrimental to their health because they can't tell when someone's joking).
Also, if she's crazy for liking ducks, then so am I. I already know that I'm crazy, though... been a tad loopy as far as I can remember, and there's no reversing it.
(Again, apologies for the little niacin rant).
