OP, are you sure you are actually dehydrated? Are you getting kidney stones?

Most people don’t need to actively concentrate on drinking liquids. Your body will tell you when you’re thirsty. It’s a weird internet fad where people try to drink like a gallon of water a day. It’s not necessarily. Your body tells you when it’s hungry and it tells you when you need to drink liquids. You’re not going to die from failure of the body signaling you to eat or drink.

Now, if you’ve had kidney stones, your doctor may tell you that you need to be drinking water.

Beyond that, excessive water drinking is just the latest fad right now. It’s not necessary.
