Been donating plasma for 4 times now. I donated plasma almost a week ago, I blacked out at the end of it, and had a seizure for about 2 seconds they told me. I weigh 246, male, 22 years old, 5 11 . I knew it was because I didn t eat enough that day, only a Greek Yogurt. I have now eaten a lot more for my next donation, does it sound like I am ready?
