You have an highly negative (Parasympathetic Dominant) Autonomic Nervous System. This will be reflected in your Metabolic Dietary Type and nutrient recommendations.
The autonomic nervous system controls most of the involuntary activities of your body. It regulates your metabolism and keeps you alive without conscious thought. It has two opposing branches: the parasympathetic and sympathetic. The parasympathetic branch (“rest and digest”) causes pupil contraction, lowering of heart rate, lowering of blood sugar, increasing of digestive secretions, and relaxation of the bladder among other things. The sympathetic branch (“fight or flight”) does the opposite. Some nutrients strengthen one branch over the other. When an imbalance exists, these nutrients can make the imbalance better or worse. Different people have different dietary requirements.
The best source of information about Metabolic Typing is The Metabolic Typing Diet by William L. Wolcott and Trish Fahey, published in 2000.
There are supplements formulated to balance the autonomic nervous system. An example of one can be found atinterclinical.com.

Parasympathetic
Usually Parasympathetic nervous system: Portion of the autonomic nervous system that is generally associated with increasing digestion and intestinal muscle activity; decreasing blood circulation and respiration.
Nervous System
A system in the body that is comprised of the brain, spinal cord, nerves, ganglia and parts of the receptor organs that receive and interpret stimuli and transmit impulses to effector organs.
