I always struggle to drink enough. Now I drink so much I get slack to refill my water bottle. I used to struggle to get through one 600ml bottle at work now I drink 3 of them. It's good cause it doesn't rely on my phone which is another distraction. I'd get busy at work forget to drink and not go to toilet all day. This is So helpful. Just a simple thing and I'm embarrassed I even need it but hey it works and water is really important for health. So glad I bought it.
