No personal experience. Giving your post a bump up, in case hasn't been seen, yet. There's not much out there for literature that discusses milk supply levels while on an SSRI, only discussion of whether it reaches milk supply. I cannot personally imagine why it would or wouldn't affect milk production? I have been under the impression that it's a combination of hormones and nutrition and a physiological need to produce.

Hopefully someone who has personal experience sees this and can better answer from personal perspective.
