Could a breastfeeding mother save her whole family during during a temp. food crisis?

I've thought about it, and wondered if my milk would be ENOUGHT TO save my family (my 2 kids and husband. My husband was a marine and they were taught to drink thier own urine incase they ever had to survive. Urine is sterile when its fresh and is mostly water so you can survive a while off of that. NASTY YES I KNOW BUT...if everyone in my family peed, and I drank it, then i either expressed my milk and gave it to them OR like my toddler could re-learn to breastfeed again, along w/ my 9 month old...........would that sustain us??? LOL i know it sounds funny and gross but its like having a milk goat w/ you all the time right??!!!
