I am diabetic and have CKD stage 4 so I have to concern myself with both diabetes and renal diet requirements when it comes to hydration. I don’t like plain water either so the suggestions of a little juice, seltzer, tea, True —, ….etc. helps the taste. I have also used Crystal Light beverage packets. There are other similar store brands & generics. You can get individual size or packets that make a half gallon. I find them in the grocery store near bottled juices and Kool-Aid packets.
