@_eric_, I got my mail-ordered bottle of the aloe vera juice you recommended (wow! big bottle for not much money!), so I'll be trying it out on my mom today. I tried some to see how it tasted and it's not bad. We'll see if I can sneak it by her consistently. She has GERD, so even if it doesn't have the desired effect on her BMs, managing the GERD will be a plus.
@Lexicon, nothing much grosses me out, either. My mom used to work in the ER and she would sometimes tell stories of the patients while we were eating. I don't remember much detail, but I do remember something about someone coming in with their eyeball hanging out of its socket, and something about intestines hanging out. I used to gross out my friends in middle school by relaying these tales during lunch!
