I love Tub Bov. I have no idea what it is except for the name of a homeopathic remedy, but it works wonders for Bright Eyes. In the last three days he's been on a higher dose, and the difference it has made to mood and general sweetness is amazing. 

I know some people don't go for homeopathy for various reasons, but I grew up with it, I trust and like my practitioner and I've seen good results from it with Bright Eyes. He hates the drops, by the way, but he'll eat the little sugar pills very happily.
