For the girly men amongst us, there is this.
Don't leave these things in the woods (preferably don't use them at all). They are not paper and they don't biodegrade.
I don't have much of a routine but I go when/where it's convenient to me - That usually means before I head out for the day, or after I get back. I don't wait until it's urgent. If I'm caught out somewhere (rare) the first place I come to gets my business. I'm not too fussy.
