A member asked:

Extreme fatigue after getting my blood drawn. is it just in my head?

No: Many people have this problem. It can be due to low iron stores-ferritin. Getting blood drawn decreases ferritin stores and can increase fatigue. Take iron if this is the problem. Others find that taking d ribose-a simple sugar only your body produces can help with this fatigue, this is great if low ferritin is not your problem.
