Already heard of your situation from Dan Franklin although I did not know about the AS aspect. I sent Dan an email on my thoughts.
For both the Army and VA you have presumptions that your condition incurred in service and/or was aggravated by service. The standard for overcomming these presumptions is clear and unmistakable evidence to the contrary. Do not allow them to call your condition EPTS w/o aggravation without providing the clear and unmistakable evidence use to overcome the presumptions. Challenge the decision if you disagree that have met this standard.
The standard is addressed in the 14 October 2008 DoD DTM. Ask your PEBLO for a copy.
