Before CD i never drank water at all, just didnt like the taste. Persevere with it. When i fill a glass i do another one at the same time so when i'm ready to drink it has got to room temp and easier to get over. I dont have a problem with water now and im glad as it has now become part of my day. I used to drink 6 tins of diet coke everyday now i occassionally have one. I worked out how many glasses i needed to make 2.2ltrs and i mark them off on a chalk board its amazing how often i go way over the minimum.
Keep focussed, you will get through this. Good luck
