talk to somebody who tasted their urine

I have got lost in the woods 8 times in the last 2 years and I’m always scared that I will be stuck for a long time. I saw some show about a man who drinked his urine to stay alive, but I always worry I can’t and will die. I wish I could just talk to somebody who did this and know what it is like so I can quit worrying about it. I thought about trying it in the bathroom so I could have a place to throw up but just thinking about it made me throw up a little bit in my mouth. My grandma says it tastes kind of like soap but I don’t see how since I don’t drink nothing with soap in it. Oh God I pray if the time comes I can do this without practice.
