I have an extremely hard time drinking water throughout the day, but I am determined to lose weight so I bought this. Now, I have ZERO problems drinking this much water everyday! You realize how easy it is getting your daily water intake by the time markers, setting personal goals and happy you achieved them as lame as that sounds. I have another bottle this size that I used to use which I could never get through, not even halfway. The key to drinking water I learned is the straw on this. It makes it very easy to drink a lot at once. Who knew a straw would solve everything?! Trust me, buy this. You'll start losing weight, your skin will look great, and you'll feel better overall.
