Be careful not to overhydrate. I drank a large bottle of water in a short time the other day and didn't replenish my body salts. Ended up with a pounding headache.
I am drinking a glass of water before every other drink i would usually imbibe; morning coffee, fruit tea break mid morning, after lunch coffee etc etc. Glass of water first.
It has the advantage that I do not forget to keep my water consumption up because, as I make one of my usual drinks, the glass is on the side in view and it reminds me to drink some water first.
