I think I see the problem. On the quackwatch site, there's a response from a well-informed angry reader which says "Scientists have discovered 90% of the seratonin in the body is produced IN THE COLON WALL. AND they've realized we have a second brain, which is located in the wall of the intestine. "
There's the problem. Your second brain is misbehaving. Best to stun it into submission with the hottest curry you can find.
