I usually post about my inlaws but today I asking about my 86 year old very able minded mother. She only drinks one cup of coffee with breakfast and one cup of tea at lunch. She " doesn't like water " . She has been complaining of being dizzy and shakey . My sister told her it's because she doesn't drink enough and I agree. Who can survive on that? I drink water all day. Man, she is stubborn ,you can't tell her anything; she thinks it's the heat ( 72 degrees at the coast?) . She does have kidney issues too due to long term use of medication for Barrett's esophogas. Advise?
