Hi there! I had the same experience as you, I found water repulsive and the smell of my own mouth/ saliva made me nauseated. I relied on ice cold water, bottled drinking water is the best. Or flavoured drinks: sugar cane, Ribena, 100 plus (no sugar options available), bubble tea (not the healthiest option), honey lemon water. I would say those few weeks were the most I spent on flavoured drinks in my lifetime, but I could not stomach regular water. If it’s carbonated and icey cold I found it to be helpful too! One friend recommended soda water which has no other additives other than it being carbonates. Try things out! I hope you find your solution!
