@jodeej Good subject, especially in this heat!
My husband fills a water bottle with ice and adds flavoring, the brand he likes is called Mio. I think its like kool-aid but it's in a little squirt bottle and you control how much you put in and adjust to taste.
I've found I drink a lot more water when I use a straw. In fact, I use the Mayo cup from my hospital stay every day, it reminds me of why I need to stay hydrated.- I had to buy a brush to clean the straw though.
I've heard of many ways to keep track of how much water you drink. marking it down never worked for me. I put a container holding the amount needed in the fridge. A friend has 6 hair ties on the neck of her water bottle and she slides one to the top every time she refills it. My husband brings 2 water bottles to work and knows he needs to refill each before he leaves for the day. We are very lucky in Oregon that we can drink the tap water, the convenience really helps!
