Water aversion

I haven't heard that term before, but right from my first chemo, I struggled with drinking water. Almost overnight I went from someone who drank close to 3litres a day, plus 2 mugs of coffee, to someone who had to push to get anywhere near 2 litres  of any fluid a day. I drank next to no plain water through chemo. I could manage sparkling water, or some very chilled water with cordial,  and occasional coffee.
I also made deliberate choices not to eat some of my favourite foods throughout chemo because I didn't want to create an aversion.
3 & 1/2 years after finishing chemo, I have no problems with water
