I had a CT scan with contrast this morning. They said to make sure I was well hydrated that morning. So I drank a litre at 7am. When I got there they gave me 600ml to drink. I left the hospital and they told me to drink LOADS of water to flush out the dye. Since I've been back I've drank 3 litres, over an 8 hour period. So today from 7am until 6pm (now) I've drank around 4.5litres.
Too much? Will I give myself water intoxication? I don't have a headache or feel sick.
