Hmm.. my migraines could be bounciness related too. I know I get them the next day if I get really upset the day before. I was REALLY bouncy yesterday and I have a migraine today. Both uber-upset and uber-bouncy are intense moods so, that could be it.
Did I tell you there may be otters living in the creek by our new place? We only see them at dusk so we haven't got a good look at what they are, but they are some kind of aquatic mammal that's for sure.
