Thank you very much for all of your responses guys.
Drinking too much water can make you thirsty via dehydration. How much salt are you taking in?
Hard for me to say as I haven't calculated salt intake. I don't really eat any salty foods and purposely never add it when Icook. Do you think two gallons is too much?

I can get through 2 litres in a night. 2 litres during the morning and afternoon at work and then easily another 3-4 litres whilst training and afterwords.

Now I'm worried! My diet is very clean, although I do cheat maybe twice a week. What things/lack of things could cause this?
Hypothyroidism makes you thirsty. You should see a Dr.
Reading up on this now, thanks.
