I'm still trying to figure out how best to handle... Yesterday I flew out to Indio and back with no issues, but an hour later I was out walking the dogs and got hit hard with an "urge" (?) bowel movement. Kept most of it in but still had to change my boxers.
This isn't a constant thing. I might go 3-4 weeks without an occurrence, or I might have three similar incidents (with or without diarrhea) in a week. There doesn't seem to be any predictable pattern.
I don't want to diaper up every day only to have the expense prove unnecessary most of the time... But when I'm caught out and about, it can be a huge problem. (What would I have done at 5500'?)
