Tyrosine, an amino acid that's usually found in meat and wheat has been found to alleviate the depression, fatigue, and irritability that make quitting cocaine so difficult. At Fair Oaks Hospital in Summit, New Jersey, addicts took the amino acid in their orange juice for twelve days. They also took vitamin C, the B vitamins (thiamin, niacin, and riboflavin), and tyrosine hydroxylase, the enzyme that helps the body use tyrosine. The results were remarkably
effective. St. John's Wort complex tablet taken in the morning is also effective in alleviating depression.
