Giving Blood, What To Expect After?

[Frankwer]

I have decided to give blood for the first time in my life. I've read that you can't do much physical activity after and you may feel drowsy the same day as well. I am a pretty active person, guessing I won't be able to go to the gym for a few days after? anything else to expect?

also, is there any long term affects to donating blood? I couldn't find anything online, I plan to start donating at least 3-4 times a year

Good info here: http://www.mayoclinic.org/tests-procedures/blood-donation/basics/what-you-can-expect/prc-20020069

I'm also sure that your donation center will have all your answers, and probably more information than you care to know...
(I think that your guess about staying away from the gym for a few days is not correct )
