I have a feeling that this is caused by anxiety attacks, when you body tends to overproduce adrenaline out of proportion with the actual need.

If you read about the underlying biochemistry of anxiety attacks excess adrenaline is produced when the brain senses a energy starvation. Adrenaline causes the blood supply to the brain to increase, thus in a way anxiety attacks is a defence mechanism. Take edible GLYCERINE obtainable from most pharmacies or Health Food Stores. Take one table spoon of glycerine and mix in a glass of water, with a dash or lemonade to improve taste. This will supply sufficient glucose to the brain to stop it from triggering adrenaline release. Search our web site for GLYCERINE. Take it before you go to the events. It also helps in sleeping.

This is a management technique, but the real treatment is treating anxiety attacks.
