Hi Andrew...
I have been told to cut out coffee completely and cut down on tea as they are both Diuretics, and also not to drink fizzy drinks, including fizzy water.
I do use squash as well as water but not to keen on it.
Strange how each Oncologist has their own list of 'do's and donts' you would have thought that with each type of treatment the diet and liquid type and volume would be, if not the same very simular.
I take a litre bottle of water everywhere with me, but when I go for treatment they tell me to make sure I empty my bladder and then drink 350ml of water 40 minutes before the start of RT to ensure the bladder is in the correct position.
This differs from what I have read from other people having the same treatment..????
