I'd love to hear any experiences of this if anyone has done it. There's a donation session in my village next month and I'm thinking of going but I'm worried about how crap I'll feel afterwards. I've never donated blood before.
I'm tandem feeding a 13mo and a 3.6yo. No health problems and I will happily eat steak all week and drink neat spatone. 
Am I bonkers for even considering it? TIA.
