Helen1000, I hear about drinking warm or at least room temperature water in different places. Why? I understand hot water to aid with BMs(doesn't help me at all). I have also read that ice water takes more energy, burns more calories. I have no idea if this is true. For me, anything but ice water, tastes yucky and nauseates me, even double filtered. When you have time would you please enlighten me on this topic. Thanx, Shelley
