My brain injury was only 4 months ago to the day and since the injury, I have struggled with staying hydrated or even wanting to drink anything. Before the accident, I tried to drink at least a gallon of water a day but now, I struggle with drinking anything. Today I managed to get down 2 12oz bottles of water but that was all I could do. I've tried flavoring the water, adding fruit, adding vitamin and electrolyte drips, etc, but nothing seems to help. It's like this with any type of liquid, not just water. Is this a normal thing or should I be more concerned?
