It can't be the easiest decision to make and reading your story I can't blame you for not wanting to put your boobs through anymore strain. If you do want to take the tablet to help dry things up, I'd assume you'd want to start taking it straight away so as to avoid the initial incoming? If that's so, and you want to feed colostrum, wouldn't pre-birth expressing and freezing what you've got be a good insurance policy in case you're not allowed to take the tablet and breastfeed colostrum after birth (just a though, I've no idea if it's safe for breastfeeding is all)? then you could just give what you've got? I did pre birth colostrum expression onto a spoon and up into syringes with DD2 for totally different reasons, but I used it and was grateful.
