I went give blood for the first time in the Savercentre the last time the mobile unit was there. It was absolute chaos and the lady on the desk said I would be better making an appointment for the next session which is in fact today. She also said that I would have to make sure that I had eaten and had a drink before giving blood. I do not get home from work until 7 p.m. so I would not have time to eat and give blood. So I did not bother to make an appointment.
