When I drink water at room temperature or water that has been cooled, I find it easy to gulp down a lot of it. In fact I need to gulp down a lot of it for my thirst to feel satiated. There is a region in the throat that needs to feel the water for some time for this happen.
I switched to drinking hot water instead of cold water a few days back. I found that I could manage to drink much less than I needed to drink with cold water. I felt satiated pretty soon - with a couple of sips. I can't gulp down hot water - it's hot - I can only sip it. And that's the key. Sip the fluids.
In the end, I drank much less than I usually do.
