Okay, I don't know how much it effects hunting (crap, that is), but I crap in the woods enough at work--so I have myself on a schedule, and I am like clockwork! I eat at the same time every day, and 20-30 minutes after I get out of bed every morning, I take a class II download, and by the time the next one rolls around, I am getting ready to go to bed. It is hard to get on a schedule with bodily functions, but once you are there, it makes life much easier.
Pretty crappy situation to be in, sorry for your luck.
