Has anyone used donor milk before?

It's becoming apparent that my supply is definitely being affected by this pregnancy. DD doesn't have nearly as many wet nappies, and the ones that are wet are not often hugely so. I've been offering more water and solids, but the fact of the matter is, she's just not ready to wean off of milk, she doesn't do much with solids other than play. I am determined to feed her from the breast through this pregnancy, but I'm starting to feel as if she needs a top up now and then, especially in the afternoon.

Has anyone used donated milk before? How were the emotional ramifications on you? Where did you access your donor milk? I'm aware of a number of avenues to explore. Anything important you want to add, or experiences to share?
