@Bornyo I have a blood pressure cuff and am on blood pressure medicine. 141/93 as of a few hours ago. Lowest I get is about 123/83.

Thanks for the warning though. That might be a stumbling block.

I have O+ which is in demand.

Thanks for the reassurance. I am going to the main blood bank here and I already went in to make sure none of my meds would disqualify me. We'll see. My pressure varies wildly throughout the day. I tried once before but was told I needed to eat more than a salad 3 hours before I went in so I have a big lunch planned.

@PipeD It might be different here in Canada. It' something I am interested in trying. If I were after some dough I would go the plasma route.
