Has anyone tried Naturally stimulating their Dopamine?

I read the research about Fibromyalgics being LOW  in DOPAMINE, which is needed to regulate and suppress the pain sensors in our bodies. So I used Applied Kinesiology to test if my body needed a natural Dopamine stimulator.  My body tested positive for the Amino Acid TYROSINE!

=Before March my pain was consistently (on the scale from 1-10) at 5 to 6 when sedentary. While walking, standing, or sitting for more than a few minutes,my pain would consistently elevate to a 7 to 8  .

March 14th '11, I Started  taking 2000 mgs of L-Tyrosine on an empty stomach in the afternoon.

=After Tyrosine supplementation, I progressively felt less pain until it became a consistent, sedentary, 2 to 4. Aggravated again by walking, Standing, of sitting, causing my pain to elevate to only a 5 to 6 !  
Every day I continued to Muscle (AK)Test, and slowly went down from 2000 mgs to 1000mgs of l-Tyrosine a day.

=On April 11th '11,  I muscle tested and got a negative AK test. So I  Stopped taking tyrosine after using it for 25 days.

=4/19- One week and a day later, my pain level was still low ,from 3 - 4.
=SLEEP!=
One night I could not sleep for 6 hours. So I took an AMBIEN!
The next day.......INTENSE PAIN !!!!!!!!!!!!!!
MY Conclusion!  AMBIEN SUPPRESSES DOPAMINE !!!!!
