Low Milk Supply with PCOS

Anyone else out there with PCOS battle low milk supply? And were you able to find anything that actually worked to increase your supply? I've done Reglan, Goat's Rue, Fenugreek, the silly tea, pumping galore, nursing as much as possible, and many other more crazy things--all to no avail. I've also spend a small fortune on visits to lactation consultants, and I've read all the books and websites and had home health visits from the hospital, etc. Right now I'm able to produce 1.75-2 ounces per feeding, which is about half of what my 4-week-old son needs. At his one-week and two-week visits it became apparent that he was not gaining weight, so I supplement with formula after breastfeeding. I've heard about women who needed to supplement with formula for upwards of 6 weeks before their supply caught up to their child's needs. Any of you have this happen? Did you do anything special to increase your supply? Like I said, pumping and Reglan didn't work for me, so I'm losing hope of being able to nurse exclusively.

Also, is there any way to keep my 2-year-old from climbing all over me while I'm trying to nurse the baby? FYI, I had the same low milk supply when trying to nurse my older boy as well. Sigh. It's hard not to feel guilty/sad/distressed about it, even though I've been down this road before.

An important note: about 1/3 of women with Polycystic Ovarian Syndrome suffer from low milk supply. Another 1/3 have oversupply, and then the last 1/3 have no issues with supply.
