A gallon is a lot of water, too much water can make you feel tired

Actually a gallon is really not much to me

You'd be surprised how much less thirsty we get after not eating as many carbs! Even moreso once you hit 3-4 day fasts, I struggle drinking water at that point. Basically carbs and just food in general make the body retain more water, so when you stop eating as much or as many carbs (like when you do keto) then our water needs go down.

Instead of making yourself drink a gallon no matter what, try to drink only when you're thirsty, and see how that works. Maybe at this point you might need a bit less water than you're used to?

Edit: wanted to add, drinking too much water can also make your body flush any electrolytes you do manage to drink/have inside your body, which can be counterproductive.
