I have hay fever, an immunity-related malady, does that count? And it's the sneezin' season now, and I'm suffering a little, like I used to. Maybe I'm a little drier, I had a bad day, couple days ago. Ummm, that's all I can report, for what it's worth.
Edit:
Yeah, come to think of it, that bad day was preceded by lotta carbs. I binged on a chocolate pudding concoction I made from the last of my coconut cream, just wanted to get rid of it the old fashioned pre-paleo way.
