Do carbs make you thirsty?

0somuchbetter0

I've been working really hard to lose weight and have lowered my carb intake dramatically. Today I treated myself to one piece of whole wheat bread -- first piece of bread in almost a month! It was delicious, but now I'm so thirsty. I've drunk about three large glasses of water in the past few hours and I'm still thirsty! I'm not worried, just curious...is this what happens when you're not used to eating bread all the time??
