have any of you ladies had up spring milk flow drink? and it worked? or your experience? I was exclusively breastfeeding and would have to pump when I was engorged since I had a good milk supply but become really depressed because it felt like I did not get a break or a chance to really rest it started to get to me. a week ago we decided to supplement with formula so my husband can feed him when I need a break. I Definitely feel so much better but now my milk supply is really low, I have enough to feed my son but not enough to pump and store when I go back to work
