Start RT on the 26 Lyn, and had to do the CT scan last week twice due to colon not being empty, ( had to use a suppository that day too ) so drank the 400ml twice that day.
Generally have two mugs of tea for breakfast, mug of tea at 11, another at 2pm, coffee at 4pm, andother mug of tea at 7pm, then a pint or two of beer at 9pm ish. Dontknow how much fluid that is but thought it plenty.
