I've been on so many diets-- have lost at leat 200lbs in my lifetime, maybe more. Every diet I've been on and lost weight, was always told to drink water. Never did it. Still lost weight. Don't know why it's necessary to drink water except that it fills your stomach.
My problem is eating at night. I can't sleep. Had the problem for many years. My father was an insomniac as well.
Maybe if there are other insomniacs here, I can talk with them at night!
Instead of eating.
