I have been trying so hard to drink tons of water and yet I feel like I'm dehydrated. I'm excessively thirsty and I feel like I can't drink enough. My lips are chapped, throat is dry and I have had a massive headache for 2 days. My milk supply is great still but I'm worried about this. Is it normally to be incredibly thirsty while breastfeeding? Should I just drink a ton and see if I can "undehydrate" myself or do I need to call my dr?
