comment #19075 Drinking urine is stupid unless you've got enough clean fresh water to flush it out. All you're doing is upping the poison level in your body.
Drinking your own urine while you're in the wilderness is a very bad idea. Yes it is a liquid and yes while it's in your body it's sterile. However the salt content in the urine itself will only help dehydrate you more after you drink it because while it is a liquid, your body can't process it.
Same idea behind why you can't drink water from the Ocean if you're stranded.
