                        Hi He may be eating something that he is allergy to.  Tske a record of whatever he gets place done the reaction  I also would get him on a daily vitamin  look into some herbs  which might help diziness, it might just be he needs oxygen to the brain try some ginkgo--I don't mean just one tablet but he may need 5 tablets  play around with it.  I will pray for him also.  God bless
