Light - Headedness

The last three times I have had my blood drawn, I began to feel light-headed, broke out into a sweat and my blood pressure dropped.  After 10 minutes of laying down, I was OK.

This never happened after a blood draw until about 1 1/2 yrs ago.

Any ideas on what could be causing it?
