Am I normal??? I am soooo thirtsy....

I am starting my 2nd week of my liquid protein fast (surgery is May 8th) and I am ridiculously thirsty.  I am talking, drinking tons and tons of water a day thirsty.  All I want to do is drink water.  Why is this?  And what causes this?  I am drinking very little broth (maybe a coffee cup 1x a day) and soup once a day.  The rest of the time I am eating protein shakes.   So I am not getting an overabundance of sodium.  Is this normal?  I'm starting to get concerned.  
Thank you!!!!

I drank lots of water but wow, all the protein I started glistening like no other!!!

I think it is the increase in protein.

Thank you ladies.  I was seriously getting worried.  I hope my body eventually adjusts, it's pretty miserable being ths thirsty all the time!!!  

Sometimes when I drink a lot of crystal light I get really thirsty because of the sweetener in it.  I drink Powerade Zero all the time.  Plain water still makes me nauseous.  Tazo Passion Iced Tea is yummy too.  It's decaf and unsweetened.   Also I was thristy all the time for a couple of weeks after surgery too.  It's hard to get the liquids down so I always seemed to be thirsty.
