Unfortunately I have only donated blood a handful of times. I wish I could do it as often as you are allowed. The reason I had to stop doing it was because I threw up and got so lightheaded that I almost fell down. After the 4th time (I waited the correct amount of times in between donations) they told me that I probably shouldn’t donate blood anymore and that I could still help by donating money : (
Not sure if being a vegetarian had anything to do with this because all of my annual checkups and blood work haven’t suggested anything like anemia or anything, so I’m not really sure what the problem is.
On the other hand, I had very good experiences when I did donate blood. It didn’t hurt and didn’t seem boring and they gave me orange juice and donuts afterwards. All of the technicians were very nice too. They just didn’t want me to barf or fall down in their facility. So I’m left to help in “other” ways.
