"How about dont drink anything after 5 pm, and pee immediately before go to bed?"
Still makes me want to pee in the morning. And until I've crawled out of the sleeping bag in winter, put on more clothes and those darn ski boots, opened the tent, crawled out of that, ran to a tree, undid all the clothes again ... it's too late. Yes, been there, done that. Wasn't pretty and I'm not proud of it.
