Would it beneficial to your health to drink your own milk?

I don't know, but i did it when i didn't want my milk supply to go down and didn't have any way to store it. Tasted pretty good. and then when i had to go back on medication, and couldn't feed anymore, I pumped a little occionally for comfort and drank it myself rather than throw it away. Figure it's gotta be better than throwing it down the drain.
