I refill my 26 oz water bottle about once every hour. It's not about sipping, I drink about a third or fourth of the bottle every time I pick it up.

I have a habit of continuing to drink when I have a glass of water in my mind. It refreshes my mind. So everytime I pick up the bottle, I drink nearly half of it just because it completely refreshes me.

So, its not really sipping but massive gulps every 10/20 mins or so.

Take bigger sips
