How much water intake for breastfeeding mom?

I was quite surprise to know that too much of water intake for a breastfeeding mom will decrease her milk supply! Context below is taken from http://www.blisstree.com/breastfeeding123/.

What’s the rule about drinking water when you’re breastfeeding? It’s the same rule for everyone, breastfeeding or not: drink enough to satisfy thirst. Drinking any more than that can actually decrease your milk supply! One study showed that consuming 25 percent more fluids than the “drink to thirst” recommendation led to a decrease in milk supply. I also learned from lactation consultant Linda Wieser at the LLL area conference that drinking more than 80 ounces of water per day can reduce a woman’s potassium levels and have a negative impact on milk supply.

So, while it’s a good idea to keep a glass of water handy next to the place where you typically nurse, there’s no need to force yourself to drink extra water. Just enjoy a glass as you feel the need!

Before I stumbled upon this site, I drank a lot of water and my colleagues used to tease me "WATER BUFFALO" (Translated to Cantonese is "sui ngau").. LOL!
