BFing through vacation tanked my pumped milk supply

CA2006

What a weird problem to have, right?  I guess I had a bit of an oversupply before, as I produced about 12 oz./day in 3 pumping sessions at work.  I just took LO on a 10 day vacation and EBFed her. Well, in my first pumping session, it looks like I may get a total of 2 oz at this point.  Bummer.  We are starting the weaning process anyway, but it's just kind of disappointing.
