A member asked:

How do i prevent feeling nauseous after having blood taken?

A doctor has provided 1 answer

?diet: Nausea is caused by an over-reaction in the lower brain. The commonest cause is diet that is so poor in the U.S. And is responsible for a great deal of changes in brain function. It is not psychological. Google my blog "oxygen, the spark of life".
