Dr. Andy Morgan at Yale Medical School studied the brain chemistry of soldiers subjected to mock interrogation techniques at Fort Bragg’s Resistance Training Laboratory. As a group, Special Forces soldiers released a greater amount of a chemical called neuropeptide Y (NPY) than did the regular infantrymen. NPY is an amino acid that helps regulate blood pressure, appetite, and memory. It also buffers the effects of adrenaline, preventing high energy from turning into wasted mania.
When I learned how to use the adrenaline I’d get from stress because of the ptsd, I might have also figured out how to stop those really bad manias I used to suffer from when my bipolar disorder was bad.
