Concerned

The last 2 or so weeks I've found myself wanting to drink all day(water, juice, milk, etc) and not really eat.

I went through a gallon of drink last night alone.

I've never been like this. I usually snack throughout the day but haven't wanted to lately.

At first I thought dehydration..but I feel like I wouldn't still be dehydrated with as much as I've been drinking.
