I was always terrible at drinking the recommend amount of fluid per day. As someone who suffers with both IBS and eczema I needed to change this. I've bought various bottles in all sorts of designs to try and achieve this but it didn't work. Then I bought the HydrateM8 tracker bottle. Having the timings on the bottle has really given me the kick up the bum to drink. I've had the bottle for over a month and have managed to drink two bottles every day. I immediately noticed some positive changes with my IBS. Yes, its more expensive than some bottles but it's worth it. Give it a try.
