I was doing dialysis in center in the US and had to beg to be able to bring a protein bar and a small bottle of water. I left work to go to the center. I would have lunch between 11:30 and noon then get on the machine at 3:00, off at 7:00. Without the protein bar and water, I would be a wreck.
Is it normal to be completely starving after a dialysis session? No matter what I eat before my session (and I usually have a small snack during), I am ravenously hungry after.
