Murph - you seem like the one to consult. Unfortunately, the nearest chapter of LLL is an hour away. I'm always thirsty when pregnant/lactating. DH makes fun of me because I always have the same bottle of water with me. He calls it my security bottle.
I used fenugreek, but I think it was too little, too late. I was only getting about 500 calories a day (I didn't even realize it) and that just isn't enough to support healthy production.
Kara - I feel the same about art. sweeteners....especially while pregnant/nursing. Honestly, my sweet tooth hasn't really come back since I did P1 all those months ago. If I do get a hankering for something sweet, it doesn't take much before it starts to make me feel icky. I guess that is a blessing in disguise.
