"I never feel thirsty..."

You may never feel thirsty so feel that you don't need to drink plain water. 

Chronically dehydrated people usually feel no thirst. The long-term dehydration has deleted their thirst instinct. The thirst will return when you start to drink more water on a daily basis. 

I read an article 13 Symptoms of Chronic Dehydration and the reason I began drinking water was because of extreme, constant fatigue. I remember the 8 glasses seeming like such a challenge back then but it helps tremendously. I started to notice other things improving too such as digestion and it's wonderful when you start to quickly notice the benefits. 

I keep thinking of those nice plump hydrated cells, which are more like grapes than raisins in my body. They are much more likely to function well because I am giving them what they need.
