There is such an simple solution to anxiety attacks. Most forms of anxiety have little to do with what you think. Your sick body makes you think in anxious ways because you are over-producing stress hormones - such as adrenaline and cortisol. This can cause you to think in a delusional way, believing that you can control your anxious thoughts with thoughts - an impossible task. These stress hormones helps your body to send glucose to your brain, whenever you brain is starved of energy. If you have hypoglycemia your brain will be starved of energy, because of unstable blood sugar levels. This will trigger the release of adrenaline. Adrenaline functions to convert sugar stores in your body, back into glucose so as to feed the brain again with energy.
Proof: use glycerine. It stops the anxiety attack. It by-passes glucose and enters glycolysis (glucose metabolic pathway) as Phosphoglyceraldehyde and is not recognized by the pancreas as sugar. Hence does not trigger excess insulin causing a hypoglycemic dip ---> anxiety reactions.
