Milk production usually depends more on protein but I would try to stay a bit higher in carbs, especially since you are already at maintenance weight. For carbs try sweet potatoes and fresh fruit instead of dried. I would stay away from the dried fruit for a couple weeks and see if you can kick that craving down a bit.
1700 is low when nursing but if you arent seeing supply drop that might be more normal for you.
The thirsty is a normal side effect when you first start primal. That goes away after awhile.
