While many other factors influence the level of these chemicals, such as hormones, heredity, drugs,
and alcohol, three neurotransmitters—dopamine, norepinephrine,

When our body has enough Dopamine we're blessed with feelings of bliss and pleasure, euphoric, appetite control, controlled motor movements, and we feel focused.
