TBI is a real problem with returning Iraqi vets. Neurology diagnosed mine from having my chimes rung by too many close mortar detonations. Exaggerated startle respnonse, light sensitibity and balance problems went unchanged for two years until I was placed on high doses of vitamin D and after a month some of the problems did improve. Vitamin D is more than for strong bones and teeth, it is vital enzyme necessary for healthy central nervous system functions. When you are placed on high doses, serial blood tests have to be done to prevent toxic levels from being reached. Thanks for your service. I'm glad to read that your getting better. Actually, vitamin D is very similar in structure to the various sex hormones.
