At least this is when I became aware of these attacks and how they worked.

 They started while working at United Space Alliance here in Huntsville, AL. I was located at Marshall Space Flight Center in the Space Shuttle Solid Rocket Booster Level II department.

I am an engineer with a mechanical engineering degree from Loyola Marymount University.

I  contacted my employer and explained in detail what was occurring. (As I stated above I believe my employer was contacted by these people and administered the chemical at MSFC (including NASA personnel) as well as at the United Space Alliance complex.) The head attacks were so severe I had to leave work sick on numerous instances. At the time these attacks were not occurring during the night, only during the daytime while at work. My employer decided to move me from the MSFC location to the United Space Alliance location just off the base. These head attacks continued, and my complaints continued. At my employer's request I submitted to physicals, blood tests, an MRI, and visited with several counselors/psychologists, all of which cleared me for work. Ultimately the decision was made by my employer to terminate my employment because these attacks continued, and my complaints and sick days continued. 

Although I became aware of these attacks
and how they worked while working at
United Space Alliance, it is entirely possible
they began prior to this point. It is however
clear they became severe and pronounced
while working, since this is how I learned the
mechanics behind them. I clearly recollect
prior to this time, however, feeling sick and
dazed on more than one occassion. They
could/probably were using these attack
techniques to cause these feelings.

As I indicated on the "Background" page, it
was my understanding they initially
attempted to get me "IN" with them. I
frequented numberious locations, such as
golf courses and parks, to attempt to make
contact, or get in; however, it never
happened. For whatever reason it is my
belief they used this telepathic attack
capability to begin the harrassment during
this initial time frame.
