If livers regenerate, would it be possible for me to donate half my liver, grow it back, then donate it again? If so, how many times can one repeat this process?

EDIT: Thanks for all the responses guys! I enjoy learning about this stuff.

No, you can only donate your liver once, mostly limited by the fact that not just any part of the liver can be sliced off and be able to fully regrow. There are two (main) lobes in the liver and each has a full set of connections needed to connect to the rest of the body (an artery, vein and bile duct). They take one of the lobes, and the remaining one just gets bigger to compensate, the taken one does not grow back.
