Liquids, check!
My friends wouldn't let me donate unless I ate something... problem is, I probably didn't eat enough. Had enough juice and sugary food right after and then my friend and I (who pushed me there in my wheelchair because wheeling elevates my pulse) went for burgers.
Still feel a little off today, but nothing compared to yesterday. Slept it off really...
Next time they come to my university, I'm definetely going again!
Thanks everyone. Hopefully next time we don't have a repeat of Christina almost passing out.
