Hello, thank you for your question.I am very sure what your problem is with the detailed information you provided. You have Orthostatic Blood Hypotension. That is low blood pressure immediately after chancing position from laying Dow to standing. That cause rapid decrease of blood pressure that affects you brain, and you faint and lay down. Probably you hit the head on the floor and that is why you have headache. To avoid this problem you should not raise or stand immediately but first stay in sitting position for few minutes until your body adapts with this position, and then you can stand.Also, you should Chat Doctor.  Coffee and cola have caffeine that helps to increase blood pressure.I hope with this new advice your problem will not occur again.
