I've heard multiple times, almost all of us will literally die of complications due to chronic dehydration. As we age, we apparently lose our sense of thirst. Any time you drink liquids other than water, be sure to drink approximately the same amount or more in clean water. I strongly advise filtered water for drinking and cooking.
Fresh lemon squeezed into clean water is amazing for alkalizing the body. An acidic condition leads to quite a few issues, including nausea in the right situations.
Set up a schedule, use timers or get the assistance of others to help you set a routine. Wake and drink 8oz of water. Drink another 8oz a few hours later. Find the balance where you're hydrated without spending all day watering the flowers.
Set the schedule and do your best to make it a lifetime routine.
You'll live longer and have fewer issues from dehydration.
